In the new period, great changes have taken place in the social and economic environment both at home and abroad, and hence new requirements have been put forward for the national food security strategy. Rethinking and resolving a series of new problems and new changes of food security under the new situation not only helps deepen the understanding of food security system, but also has positive significance to promote the upgrade of agricultural industry and rural development under the background of supply-side structural reform. At present, food security in China falls into a strange circle, which is the coexistence of excessive production, import, inventory, subsidy and waste. There are large differences in understanding and viewpoints on food security issues among different disciplines such as traditional agricultural school, economic school and resource environment school, which reflects the complexity of food security issues. In the meantime, the concept and connotation of food security, from emphasizing the amount of food basic supply to the individual purchase ability in the market, and to the quality of life and the ability to resist risks, are constantly enriched and extended. It is the inevitable choice and demand of social and economic development. Faced with a new era, under the background of the periodic and structural oversupply of grain in our country, it is imperative to build a new food security strategy of “nutrition, green, diversity, and openness” in our country on the basis of grasping the connotation and characteristics of China’s food security.

新时代国内外环境发生了深刻变化,对国家粮食安全战略提出了新要求。重新思考和梳理新形势下粮食安全面临的一系列新问题和新变化,不仅有助于深化对粮食安全问题的系统认知,同时对推动供给侧改革背景下农业产业升级和农村持续发展具有积极意义。目前,我国粮食安全领域陷入产量多、进口多、库存多、补贴多和浪费多的“五多怪圈”。传统农学派、经济学派和资源环境学派等不同学科对粮食安全问题的理解和观点存在较大差异,体现了粮食安全问题的复杂性。粮食安全概念从强调对粮食量的保障和供给、强调市场条件下的个人购买能力,到从基本保障提升到生活品质、强调国家对风险的抵御能力,内涵不断充实和延伸,是社会经济发展的必然选择和要求。现阶段应当从全产业、多尺度、精准化、多维度、多因素视角全方位解读粮食安全的最新内涵。面对新时代,在我国粮食出现阶段性、结构性供大于求的背景下,构建“营养、绿色、多元、开放”的新时代粮食安全观势在必行。

In 2017, the net import of virtual farmland of bulk agricultural products in China reached 67.84 million ha and the external dependence was 33.4%, in which Brazil and the United States are the major importing countries. In China, large import of land-intensive agricultural products focused on soybeans ensures a certain degree of food supply. However, implementing the "going- out" strategy of agriculture can fundamentally protect China's food security. Although China's overseas agricultural investment has increased year by year, the enterprises have poor control in overseas agricultural resources and high production risks due to lack of long-term investment strategy guidance. For protecting China's food security, from the strategic perspective of building a community with a shared future for mankind and enhancing global agricultural product supply capacity, China should choose the best overseas investment area to develop international soybean and palm oil and other types of edible oil and fat feedstocks with large import volume and high foreign dependence in priority; encourage the multiple enterprises to join the overseas agricultural resources development; cooperate deeply with the investment destination country through the "order + farmer" model and integrate into the global agricultural trade system.

2017年中国大宗农产品虚拟耕地净进口量达到6784万hm²,对外依存度为33.4%,其中巴西和美国是主要的进口来源国。以大豆为重点的土地密集型农产品的大量进口,在一定程度上保证了中国粮食供给,但要从根本上保障中国粮食安全也应实施农业“走出去”战略。尽管近年中国海外农业投资逐年增加,但由于缺乏长远的投资战略指导,海外农产品资源的控制能力差,生产风险高。为此,为保障中国粮食安全,应从构建人类命运共同体、提高全球农产品供给能力的战略高度,选择最佳海外投资区域,优先开发中国进口量大、对外依存度高的国际大豆和棕榈油等油脂油料资源;扶持多类型企业主体参与海外农业资源开发;在农业投资目的国通过“订单+农户”模式进行深度合作,并融入全球农产品贸易体系。

How to evaluate energy geo-economics cooperation relations of exporters and importers have become the important research issues for geography. Russia is one of the most important producers and exporters of crude oil and natural gas in the world, and has been the main source of imports of crude oil and natural gas in china and Japan since 1990s, which resulted in the certain structure of energy geopolitical and energy geo-economics relations among the three countries. This article attempts to build an evaluation model for evaluating energy geo-economics cooperation relations between energy exporter (Russia) and energy importers (China and Japan) in the Russian Far East-Pacific crude oil pipeline construction from 1995 to 2016. The results show that: (1) The scissor difference has been recorded between the rising energy geo-economics cooperation relations index of Russia with China and the declining that of Russia with Japan, and its intersection appeared in 2012. (2) Sino-Russian energy geo-economic cooperation relations have undergone an increasing variation, namely from wave shape variation (1995-2002) and oblique “N” shape variation (2003-2008) to rapidly rise variation (2009-2016), and Sino-Russian energy geo-economic cooperation has entered a stage of rapid development since 2008. (3) During the same period, variation of energy geo-economic cooperation relations between Russia and Japan has showed a downward trend, namely from wave variation and rapidly drop variation to fluctuating decline, and Japan has become one of the energy importers with less volume from Russia. The increasing sustainable progress of energy geo-economic cooperation relations between Russia and China will be recorded in the perspective of the Sino-Russian comprehensive strategic partnership of coordination in the future.

俄罗斯是世界重要的油气资源生产国和出口大国,自20世纪90年代以来,就逐渐成为中国和日本油气资源主要进口国之一。本文通过构建能源地缘经济关系评价模型,以俄罗斯远东—太平洋原油管道为切入点,对该管道建设中的1995—2016年俄罗斯与中日两国能源地缘经济合作关系进行了定量评估。结果表明：①中俄能源地缘经济合作关系指数由1995年的0.079不断攀升至2016年的0.693,日俄能源地缘经济合作关系指数由1995年的0.992下降至2016年的0.266,两条指数变化曲线交汇于2012年并呈现“剪刀差”状。②中俄能源地缘经济合作关系演变轨迹呈现出波浪式平稳（1995—2002年）、斜“N”型上升（2003—2008年）和快速上升的变化趋势（2009—2016年）,2008年后,中俄能源地缘经济合作进入快速发展阶段;同期的日俄能源地缘经济合作关系演变轨迹呈现出波浪式平稳、快速下降和梯级下降的变化态势,当前日本仅为占俄罗斯原油出口量份额极少的一个出口目的国。未来,随着中俄全面战略协作伙伴关系深入推进,中俄能源地缘经济合作关系将继续向好发展。

Under the reshaping of the world political and economic map, regional grouping promoting the adjustment of global governance, and the change of international system brought about by the game of great powers, it is relevant to sort out the historical context of geo-economics. Based on the clarification of the geo-economic academic thought, this paper selected WOS and CNKI as the literature retrieval library, and used CiteSpace to sketch out the knowledge map of geo-economic research. The results of this study are as follows. Firstly, the geo-economic academic trend of China and the West has experienced the "greening period -development period - backtracking period". The budding period still exists in realistic political logic. The development period is liberal. The backtracking period re-emerged the national political connotation. Secondly, in recent years, the intensity of geo-economic research in the West is much higher than in China. The western authors are mainly distributed in the US, Russia, UK and Italy. The domestic scholars are mainly concentrated in the Chinese Academy of Sciences, Yunnan Normal University and East China Normal University. Thirdly, geo-economic literatures have a clear knowledge base and knowledge network, and the highly cited literatures are derived from the works of geography or political science. Geo-economics forms a knowledge structure based on power, and space as the logical starting point, economy as the logical spindle. The evolution process of hot topics is highly coupled with the development of academic thought. Competition in science and technology will become the focus of geo-economics research in the future. This paper suggests that geo-economic research should build a geo-economic theory with win-win cooperation and open development, and strengthen empirical research.

在科技革命重塑世界政经版图、区域集团化推动全球治理调整、大国博弈带来国际体系变革的背景下，梳理地缘经济研究脉络对于提升地缘经济理论品质具有重大意义。本文在厘清地缘经济思潮发展的基础上，借助Web of Science和CNKI数据库，运用知识可视化工具探究中西方地缘经济知识图谱的演进过程，研究结果如下：①在学术思潮发展层面，中西方地缘经济思潮经历了“萌芽期—发展期—回溯期”，萌芽期存在现实政治逻辑，发展期转向自由主义思潮，回溯期再度涌现国家政治内涵。②在时空演进层面，近年来西方地缘经济研究强度远高于国内，西方作者主要分布在美国、俄罗斯、英国和意大利，国内学者主要集中在中国科学院、云南师范大学、复旦大学等高校和科研机构。③在知识网络层面，地缘经济存在较强的学科交叉属性，拥有明确的知识基础，高被引文献源于政治学或地理学，形成以权力为逻辑基础、空间为逻辑起点、经济为逻辑主轴的知识架构，热点议题演进与学术思潮发展高度耦合，科技竞争将成为当前乃至未来很长一段时间的研究重点。最后，本文认为国内地缘经济研究应突破西方的理论桎梏，构建以合作共赢、开放发展为核心的理论体系，在方法论上应强化定量分析和实证研究。

 

Using the global commodity trade data from 1996 to 2016, this study employed exploratory spatial data analysis to reveal the spatial model of the global geo-economic cooperation, and further explained the spatial mechanism of the global geo-economic cooperation by constructing the SARAR model. Results are: Firstly, the global geo-economic cooperation has showed positive spatial correlation and formed a core-periphery pattern, showing the trend of multi-polarization and modularization. Secondly, the spatial dependency of the global geo-economic cooperation has been transmitted and driven by the flow of production factors and the international division of labor. The scale of nation has acted as the foundation, the endowment of the production factors as the endogenous incentive, innovation as the engine, and the political fragility as the important barrier of the geo-economic cooperation. The transnational flow of innovative factors has weakened the spatial dependency of the geo-economic cooperation. Thirdly, China should progressively distribute the geo-economic resources, following the three-ring principle of ‘neighboring countries- Eurasian region- whole world’. China should take advantage of its scale and factor endowment, enhance its international competitiveness in scientific and technological innovation, and formulate the geo-economic policies in the light of different countries. Strategically, China should maximize the geo-economic leverage effect by stimulating the penetration of geo-economy into geo-politics.

运用1996—2016年全球各国商品贸易规模的面板数据，借助探索性空间数据分析方法揭示全球地缘经济合作的空间模式，构建空间误差混合回归模型进一步解释全球地缘经济合作的空间机理，得出如下结论：① 全球地缘经济合作存在空间正相关，呈现出“核心-边缘”的空间模式，表现为板块化和多极化的发展趋势；② 全球地缘经济合作的空间依赖性受到生产要素流动与国际分工的传导与驱动，国家规模是地缘经济合作的基础因素，生产要素禀赋是地缘经济合作的内生动力，创新是地缘经济合作的引擎，政治脆弱性是地缘经济合作的壁垒，地缘经济合作的空间依赖性在创新要素跨国流动影响下趋于弱化；③ 中国需在空间上遵循“邻近国家-欧亚区域-全球范围”的三环递进原则，有层次地布局地缘经济资源，在内容上发挥规模优势和要素禀赋优势，强化科技创新国际竞争力，有差异地制定地缘经济政策，在策略上激发地缘经济对地缘政治的渗透效应，最大化地缘经济杠杆作用。

With the gradual shift of the global economic center of gravity to the Asia-Pacific region and the increasingly close regional geo-economic linkages, the strategic position of the South China Sea has become increasingly prominent, and the surrounding regions of the South China Sea have become an important global strategic region and Asia's most important international geopolitical problem regions. Research methods of social network analysis and modified gravity models are applied to explore the evolution and trend of the geo-economic relationship between countries outside the region and in the surrounding regions of the South China Sea from the perspectives of trade, investment and tourism. The results show that: (1)From 2005 to 2019, the trade linkages between countries outside the region and in the surrounding regions of the South China Sea have become increasingly close, but the imbalance of trade cooperation is more prominent, and the intra-regional export trade network presents a relatively stable network structure with China as the core and Laos, Brunei and Cambodia as the periphery. (2) The investment scale of countries outside the region in the surrounding regions of the South China Sea has increased significantly, but the polarization of the investment scale is more obvious, and the investment location has shown a shift from high concentration to gradual diffusion. (3) The inbound tourism flow of countries outside the region continues to grow, the tourism network has evolved from a single core of China to a dual core network structure of China and Thailand, and tourism destinations have become increasingly diversified. (4) The strength of geo-economic linkages between countries outside the region and in the surrounding regions of the South China Sea has decreased, but generally, the strength of geo-economic linkages with the nine ASEAN countries has increased. Although the countries outside the region, represented by the United States and Japan, have gradually weakened their geo-economic linkages with China, the overall geo-economic linkages network still presents a network structure with China as the main core and Thailand and Singapore as the secondary cores.

随着全球经济重心逐渐向亚太地区转移以及区域地缘经济联系日趋紧密,南海战略地位日益凸显,南海周边已成为全球重要战略区域和亚洲最重要的国际地缘问题区域。运用社会网络分析法、修正引力模型等方法,从贸易、投资、旅游等视角切入探究域外国家与南海周边区域的地缘经济联系演变及态势。结果表明：① 2005—2019年域外国家与南海周边区域的贸易联系日益紧密但贸易合作的非均衡化现象较为突出,域内出口贸易网络呈现以中国为核心,老挝、文莱和柬埔寨为边缘地带的相对稳定网络结构特征。② 域外国家对南海周边区域的投资规模显著提升但投资规模的两极化差异态势较为明显,投资区位呈现由高度集中向渐进式扩散转变态势。③ 域外国家入境旅游流持续增长,旅游网络由中国为单一核心演变为中国和泰国为双核心的网络结构,旅游目的地日趋多元化。④ 域外国家与南海周边区域地缘经济联系强度有所降低,但与东盟9国地缘经济联系强度整体上升;虽然以美日为代表的域外国家逐渐减弱与中国的地缘经济联系,但地缘经济联系网络整体仍然呈现以中国为核心,以泰国和新加坡为次核心的网络结构。

As an expansion area of international cooperation under the Belt and Road Initiative, South America is of great importance for China to enhance geo-economic status and expand geo-economic space. Based on trade, investment, tourism, transportation and politics, this paper establishes a multi-dimensional index system of geo-economic linkages intensity and analyzes the important characteristics of the geo-economic linkages intensity between China and countries in South America by using the gray correlation TOPSIS method and geographically weighted regression model. The results show that: (1) The geo-economic flows between China and South American countries show an overall increasing trend during 2006-2015. (2) China and South American countries have an unbalanced development in geo-economic linkages elements. The geo-economic linkage of transportation is higher than that of politics, tourism, investment and trade. (3) The geo-economic linkages intensity between China and South American countries are at a low level and varies significantly among countries. (4) The geo-economic linkages intensity between China and South American countries is slowly increasing, and the changes in spatial pattern are small year by year. (5) Gross domestic product, population size and cooperative goldenstein factor are the dominant factors influencing the geo-economic linkages intensity between China and countries in South America. Market is the most important driving force for geo-economic linkages intensity between China and countries in South America. Resource endowment has little effect on the geo-economic linkages intensity, while geopolitics has a significant effect on the geo-economic linkages intensity.

南美洲作为“一带一路”倡议国际合作的拓展方向区,对于提升中国地缘经济地位和拓宽中国地缘经济空间具有重要的意义。基于贸易、投资、旅游、交通和政治,本文建立多维度的地缘经济联系指标体系,运用灰色关联TOPSIS法和地理加权回归模型,解析中国与南美洲国家地缘经济联系强度的重要特征。结果表明：① 2006—2015年中国与南美洲国家的地缘经济要素流整体呈增长趋势。② 中国与南美洲国家地缘经济要素联系发展不平衡,交通联系强度高于政治、旅游、投资和贸易。③ 中国与南美洲国家地缘经济联系强度偏低,且差异显著。④ 中国与南美洲国家地缘经济联系强度提升缓慢,空间格局年际变化不大。⑤ 国内生产总值、人口规模、合作戈登斯坦因子是重要的地缘经济联系强度影响因子。市场是中国与南美洲国家地缘经济联系强度最重要的驱动力,资源禀赋对中国与南美洲国家地缘经济联系强度作用有限,地缘政治对中国与南美洲国家地缘经济联系强度作用显著。

With the advancement of globalization and market economy, geo-economic relation has increasingly attracted scholars' attentions. Trade data, including import and export flows, has dominated the geo-economy research owing to its availability and representativeness. However, this might incline geo-economy research toward trade studies and disregard the importance of other international economic components, such as investment. Combining investment and trade data in doing geo-economic analysis could provide us with a more comprehensive understanding of economic relations between countries. Taking China, the US and Northeast Asian countries as an example, this paper explores the patterns of geo-economic relations between these countries, inspects the driving forces and formation mechanism of the patterns, and also makes comparison between China and the US. As a typical region with unbalanced politics and economy and greatly influenced by both China and the US, Northeast Asia can be a salient sample for geo-economic research. A geo-economic streaming potential model is proposed to evaluate comprehensive geo-economic relations which take into account both trade and investment. The conclusions are as follows. First, from 2000 to 2016, the geo-economic relations between China and Northeast Asian countries were strengthened, during which trade flow constantly occupied the dominating position. However, since 2012, the proportion of investment in geo-economy has increased rapidly. Second, the geo-economic flows between China and the US were the strongest with the fastest growth. The geo-economic flows between China and Japan, South Korea were increasing, while those between China and Russia, Mongolia and North Korea had limited influence. Third, both China and the US had expanding geo-economic flows with Northeast Asian countries and similar distribution pattern. Two major differences are also noted. One is that driving forces are different with China's geo-economic relations driven by trade flows and those of the US driven by investment. The other difference is that China's connections with Russia, Mongolia and North Korea have been strengthened while the US has been trying to maintain strong geo-economic relations with Japan and South Korea.

由于全球化和市场经济在全球范围内得到普遍认可,在各类地缘关系中地缘经济关系成为最活跃也是研究最多的一类。本文从中国与东北亚各国地缘经济研究现状入手,基于流量数据建立地缘流势模型来探寻地缘经济复杂关系背后的规律性因素,并通过对比中美两国与东北亚的地缘经济关系分析其驱动机制,得出如下结论：① 2000—2016年中国与东北亚地缘经济联系不断加强,其中贸易联系明显强于投资联系,但投资联系在2012年后得到了飞速的发展。② 中国与东北亚地区的总体经济流势呈现上升态势,其中贸易流势起主导作用,中美地缘经济流势表现最强、增速最快,中国对日、韩两国的地缘经济流势强度不断显现,中俄、中蒙、中朝三股地缘经济流势虽然近年来不断增长但对区域整体地缘经济关系影响有限。③ 中美两国与东北亚的地缘经济流势均呈现出波动上升的趋势,并在国家关系分布上较为一致;两国在地缘经济差异主要体现在两个方面：一是驱动因素不同,中国以贸易关系为主而美国主要依赖投资驱动;二是空间分布差异开始显现,美国与东北亚的地缘经济关系越来越集中于中、日、韩三国,而中国与俄、蒙、朝三国联系开始不断加强。

Based on the theoretical and empirical foundations of the gravity model, this article systematically investigates the determinants of international tourist arrivals to China. Various origin–destination (O-D) linked factors accounting for the economic, political and social/culture preferences between China and its tourist origins are particularly explored. Utilizing a panel data set of tourist arrivals to China from 21 countries from 1995 to 2014, the results suggest that the basic gravity determinants all have significant effects on tourist arrivals to China. Furthermore, four O-D linked factors are found to be significant in explaining the number of international tourists and have a greater tourist-enhancing effect. In particular, overseas Chinese, proxying for social/culture-preferential relationships, have caused significant increases in tourism arrivals to China of approximately 120% when the percentage of ethnic Chinese in the origin countries’ population is more than 1%. For China to be chosen as a manufacturing and processing centre by international enterprises, various O-D relationships are important but neglected factors of Chinese tourism patterns, with important policy implications.

The Pan-South China Sea economic circle is one of the most active regions in the global economy. Strengthening the geo-economic relations between Hainan Free Trade Port and neighboring countries is conducive to promoting the construction and improving regional economic and trade cooperation's level. This paper constructed a geo-economic relations index system from the aspects of trade, investment, industry and finance, and explored the evolution and influencing factors of the geo-economic connection pattern between Hainan Free Trade Port and Pan-South China Sea countries through entropy method and grey correlation method. The study found that: ①From 2005 to 2019, the geo-economic connection between Hainan Free Trade Port and Pan-South China Sea countries is at a low level, and there is no significant improvement. Among them, trade relations are relatively close, and investment, industrial and financial relations need to be further strengthened. ②From 2005 to 2019, the temporal and spatial pattern of geo-economic connection between Hainan Free Trade Port and Pan-South China Sea countries changes significantly, and Myanmar and Singapore fluctuate greatly. Overall, Hainan Free Trade Port has the strongest economic relations with Singapore, Vietnam, Brunei and Indonesia, and the weakest economic relations with Laos, India, Bangladesh and Sri Lanka. ③Market is the primary influencing factor of Hainan's geo-economic relations. Cost constraints have a certain impact on the economic relations, while the impact of production factors is limited.

泛南海经济圈是全球经济要素最活跃的地区之一。加强海南自贸港与周边国家的地缘经济联系有利于推进海南自贸港的建设，提升区域经贸合作层次与水平。本文基于贸易、投资、产业、金融等方面的综合考虑，构建地缘经济关系指标体系，并通过熵值法和灰色关联法探究海南自贸港与泛南海国家的地缘经济关系演变及其影响因素。研究发现：（1）2005—2019年，海南自贸港与泛南海国家的地缘经济关系一直相对较弱，且未出现显著提升。其中，贸易联系相对紧密，投资、产业、金融联系有待进一步加强。（2）2005—2019年，海南自贸港与泛南海国家地缘经济关系的时空格局变动明显，缅甸、新加坡波动幅度较大。总体来看，海南自贸港与新加坡、越南、文莱、印尼的经济联系最强，与老挝、印度、孟加拉国、斯里兰卡的经济联系最弱。（3）市场是海南自贸港地缘经济关系的首要影响因素，成本约束对地缘经济具有一定影响，而生产要素的影响相对有限。

With the implementation of China's "going out" strategy, the cooperation between China and South America has developed rapidly. South America is located between the South Atlantic and South Pacific. It is rich in oil, grain and mineral resources, and is an important energy and grain production base in the world. In recent years, The United States, European Union, Russia, Japan and other great powers have been highly concerned about and involved in the South American region, which has made the geopolitical environment very complex. As China deepens its cooperation with this region, it also takes into account the pressures of competition and intervention by other powers. Based on the geopolitical relations reality in South American, this paper analyzes geo-influence of the great powers from the perspectives of geopolitics, geo-economy, geo-culture and geo-military respectively, which provides an analytical idea for the interpretation of the complex geo-environment in South America. It shows that the great powers exert different geo-influence in South America, which is manifested by the different means and the significant differences between different countries.

How large are the benefits of transportation infrastructure projects, and what explains these benefits? This paper uses archival data from colonial India to investigate the impact of India's vast railroad network. Guided by four results from a general equilibrium trade model, I find that railroads: (1) decreased trade costs and interregional price gaps; (2) increased interregional and international trade; (3) increased real income levels; and (4) that a sufficient statistic for the effect of railroads on welfare in the model accounts well for the observed reduced-form impact of railroads on real income in the data.

The cooperation of arable land resources in the China-Mongolia-Russia economic corridor is of great significance to the joint construction of “the Belt and Road” and the promotion of the China-Russia comprehensive strategic partnership of coordination for a new era. Based on remote sensing, field surveys, statistical analyses and other methods, this study comprehensively revealed the distribution pattern of arable land resources in the China-Mongolia-Russia economic corridor, analyzed the main constraints on the development and utilization of arable land resources in the China-Mongolia-Russia economic corridor, explored the main problems of China's cooperative development of foreign arable land, and proposed measures and suggestions for the cooperation of arable land resources in the China-Mongolia-Russia economic corridor. It is shown that arable land resources are abundant in the China-Mongolia-Russia economic corridor, mainly concentrated in the basins of the Moskva river, the Volga river, the Ob River, the Yenisei river, the Amur river, and the Baikal basin in Russia. The key pilot demonstration areas include Altai Krai, Amur Oblast, Khabarovsk Krai, Jewish Autonomous Oblast, Primorye Krai, Novosibirsk Oblast, Omsk Oblast, Republic of Buryatia, and so on. The proportion of high-yield arable land in the China-Mongolia-Russia economic corridor is not high. The arable land area and high-yield arable land area in the Russian part of the China- Mongolia- Russia economic corridor account for about 60% and 74% of that in the whole economic corridor, respectively. The unused arable land area in the Russian part of the China-Mongolia-Russia economic corridor accounts for nearly one-half of that in Russia, with huge land development potential, which is about 95% of the unused arable land area of the China-Mongolia-Russia economic corridor. China-Russia agricultural cooperation is a mutually significant win-win move between both sides. In the future, great attention should be paid to the cooperation of cultivated land resources in the China-Mongolia-Russia economic corridor, and the experiences of Japan, South Korea and other countries should be used to promote the development of China-Mongolia-Russia cooperation in arable land resources and agriculture. China and Russia could innovate the cooperation models of arable land resources, strengthen the construction of the China-Russia agricultural free trade zone, and try to build a China-Russia cooperation innovation demonstration zone. Moreover, both sides could strengthen and upgrade the agricultural product logistics and trade channels of the China-Mongolia-Russia economic corridor, and improve the facilitation level of international cooperation in arable land resources. These would be used as the key direction of China-Russia comprehensive cooperation.

中蒙俄经济走廊耕地资源战略合作对于“一带一路”共建、加强中俄新时代全面战略协作伙伴关系意义重大。本研究综合运用遥感影像解析、野外实地考察、统计分析等方法,揭示了中蒙俄经济走廊耕地资源分布格局,剖析了耕地资源开发利用的主要制约因素;研究了中国对外耕地合作开发的主要问题,探索提出了中蒙俄经济走廊耕地资源合作对策建议。中蒙俄经济走廊耕地资源丰富,主要集中在俄罗斯欧洲部分莫斯科河和伏尔加河流域,以及鄂毕河流域、叶尼塞河流域、阿穆尔河流域与贝加尔湖流域等地。中蒙俄经济走廊俄罗斯部分耕地面积和高产耕地面积分别占经济走廊的60%和74%左右;而经济走廊俄罗斯部分未利用耕地面积占俄罗斯未利用耕地面积的近50%,占中蒙俄经济走廊未利用耕地面积的95%左右。今后应高度重视中蒙俄经济走廊耕地资源合作开发,推动中蒙俄耕地与农业合作自由化发展,可探索在阿穆尔州、犹太自治州等地率先开展中俄毗邻重点耕地国际合作创新示范区建设和农业自贸区建设,扩展延伸经济走廊耕地产业链和价值链,共建多元稳定的中蒙俄经济走廊农产品物流贸易通道。
