Abstract:

Optimizing industrial structure is an important research object of human-economic geography, and it is also the object of government departments to strengthen macro-control. This has become even greater problem that China has entered the "new normal" in recent years. The study uses a multi-regional input-output model, with linear programming to build an optimal model of industrial structure as well as a model of optimization degree under the energy constraint. The results show that: (1) Under the constraint of energy conservation, the optimization degree of industrial structure of Anhui province is the highest (0.763), while that of Shanxi is the lowest (0.662). Under the constraint of employment, the optimization degree of industrial structure of Jiangxi is the highest (0.768), while that of Shanxi is the lowest (0.659). (2) Under the constraint of energy conservation, the optimization degree of industrial structure is negatively related to the energy consumption per unit of output value and the proportion of heavy industry. Under the constraint of employment, the optimization degree of industrial structure is negatively related to the proportions of state-owned economy and large enterprises. (3) Considering different orientations of energy conservation and employment, the directions of industrial structure optimization of the six provinces in central China are obviously different. (4) As a whole, central China should maintain or moderately increase the proportion of resource-based industry, greatly raise the proportion of manufacturing including transport equipment and communication equipment, computers and other electronic equipment, moderately reduce the proportion of smelting and pressing of metals and manufacture of non-metallic mineral products. In terms of services, central China should greatly increase the proportions of the production and supply of gas and water industry and tourism, moderately or greatly reduce the proportions of wholesale and retail trade and catering, and maintain or moderately reduce the proportions of transportation and warehousing.
