| In the development of planning economy in China, a number of resource-based cities came into existence, whose pillars of economy are mostly energy and raw materials. After a long period of exploitation, the cities have entered into the stage of maturity and then decline. Then a series of problems arise, like the rise of exploitation cost, environmental pollution, financial shortage, less employment, and so on. This thesis aims to tentatively conduct explorations of the economic restructuring and industrial transition.Firstly, it is pointed out in the thesis that there is a need for the city of Tongchuan to restructure its industry and conduct the transition, based on the conclusion that the city is typically resource-based. The problems with the current economic development in Tongchuan are analyzed and they are respectively inappropriate industrial structure, its overload, excessive dependence on coal exploitation, serious environmental pollution, employment, etc.Secondly, the basic patterns, industrial furtherance, substitution and multi-compound, for industrial transition, their implications and conditions are analyzed, on the basis of the industrial transition theory. In the five terms of resource allocation, economic state, industrial relationship, production technology and level, and policy, the respective influence on the substituted industry is analyzed. Then an evaluation system is built on the considerations of income elasticity of demand, industry interaction coefficient, industry chain coefficient, industrial composition, per-tax profits per 100 yuan, contrastive concentration rate, productive rate increase of all elements, employment rate. By the standards mentioned above and with the principal components analysis, the possible substitute industries, as an optional choice for the industrial transition in Tongchuan, are analyzed carefully.Thirdly, the cost of industrial transition is defined, and its flow and opportunity cost are generalized. Subsequently, the relevant implementation cost and risk cost are analyzed, including the withdrawal of traditional industries, environmental improvement and ecological recovery, the establishment of social security system, the separation of the social functions of resource-based enterprises, the barriers of substitute industry's introduction, fund raising, transitional conflicts, etc. And, the way to share these costs on government and enterprises are put forward. Finally, the policy mechanism to insure smooth industrial transition is analyzed, and the establishment and function of the systems of exploitation compensation, aiding declining industries, supporting substitute industry are discussed. At the end, the measures to further economical restructuring and transition in Tongchuan are offered, considering its diversity and supplement. |
