持续发展是我国的基本国策，各级政府要使其所在区域实现持续发展的目标，必须考虑在保护环境生态的基础上，通过相应的经济起步和发展措施，逐步提高经济发展水平，以满足人口的不断增长以及相应的物质“享受”的需求增长。区域开发只有处理好生态环境、经济发展与需求增长等三方面的关系，做到近、中、远期滚动协调发展，并增强开发措施的可操作性，才能真正实现区域可持续发展的目标。行业开发是区域发展的部门组成，要保证行业的持续发展，首先要求行业本身能不断发展，并符合该行业本身的发展规律，才能加速开发，与区域持续发展相协调，正确处理企业经营、行业管理、区域开发三者的关系，其间，政府和企业的决策行为具有重要作用。

Sustainable development has become a state basic policy in China, and governments at various levels are struggling to realize it. Localities must take actions in several steps to reach the goal of sustainable development. The most important step is, based upon enivronmental conservation, to enhance the level of economical development by means of all possible meausres, and to satisfy qualitatively and quantitatively the increasing demands both of population growth and living standard improvement. In order to really achieve regionally sustainable development, the relationship between ecological environment conservation and economical development and demands satisfaction must be dealt with well and coordinated with each other, the development should be planned in short term, middle term and long term respectively and in a compatible or trundling way; and all policies and measures should be operationalizing. Regional development can be seen as a complex of the development of various industries. Thus the development and sustainability of industries is the guarantee for regional development. This topics may be discussed at three levels: 1. How to ensure the development of industries and their enterprises? Only if the enterprises’ production keeps profitable, industries can develop or even be enlarged. When the marginal benefit of the products decreases the scale of enterprises will not be enlarged. In the situation of market process adjustment, enterprises can achieve economic efficiency only if they reach certain scale. Enterprises with products lack of competition capacity will not get profit and may wither and even go bankrupt. 2. The development and sustainability of an industry should be conformed to the law of the industry. So industries can sustain their development only if continuously innovate and develop new products so as to advance to a new stage of development and occupy new markets. 3. Industries development should be long sighted without eagerness for quick success and instant benefit. Therefore, the environmental protection should be emphasized. Production could not damage the regionally ecological balance between nature and society, through any kind of pollution (including eyesight pollution and ethic pollution, in extensive comprehension). Exploitation profit of industry should not be at the cost of social diseconomy. Short sighted behaviors run in the opposite direction of sustainable development, and will be punished by the feedback mechanisms of environment and socity. The roles of government are improtant in coordinating the enterprises’ operation and industries’ management with regional development. By means of policies, the government can direct the development of industries and enterprises, at the three levels mentioned above, to be beneficial to overall regional development. It should be emphasized that the key of sustainable development in underdeveloped and developing regions is the current starting measures. These can be identified stey by step through regional diagnosis, causal analysis and CI (certified identity) design. Regarding the concept of sustainable development, more attention is unilaterally paid to ecological environment at present, and the importance of the function of economic growth is relatively ignored. In fact, sustainable development will not come true without the support of economy. Ecological and social effects can be seen as the goals of sustainable development, while the economical benefit is the key of operationalizing sustainable development. The development of industries is closely related to regional economy, so should be studied deeply in the research on regionally sustainable development. Development strategies of industries are also discussed and suggested in this paper, taking tourism, agriculture and industry (narrow sense) as examples.
