Theory Of Economic Transformation Of Resource-based Cities And Models Optimization Research

Resource-based cities is a kind of industrial cities relied on natural resources supply and formed by population gathering with the development of extractive industry and relative social production . There are 118 resource-based cities in China, which account for 18 percent of the total and have a total population of 154 million. With the development of China's market economy and acceleration of its industrialization process, most resource-based cities have experienced their establishment, palmy days and decline all because of mining, as well as long-term disorderly development and imperfect policies. How to resolve the global problem that the city ruins with the exhaustion of mine remains a big research subject for governments at all levels and correlative institutions.Experts domestic and abroad have made research from different points on economic transformation of resource-based cities and raised theories. Aiming at the root of problem and making intensive study on the law of development of resource-based cities in China, a dualistic balancing development theory have been raised on the basis of theories of regional economic development, of sustainable development, of ecological economy, of cycle economy, and of industrial development. The theory is consonant with the scientific view of development and enjoys guide significance to economic transformation of those resource-based cities on different stage.The main problem for economic transformation of resource-based cities is to look for leading industries and probe optimum mode for transformation. The selection of leading industries and mode of transformation must be in accord with three standards: social & economic quick and good development, resources-saved development, environmental improvement and protection. Guided by the dualistic & balancing development theory, according to development stage and industrial chain and researching the each comparative advantage and the industrial, regional and environmental relations, four modes of transformation have been brought forward for industrial development as follows, deepening cultivation, external extending, potential exploration and strengthening, contraction and replacement. On the basis of the four modes and depending on the reality of Tongchuan city, the economic transformation mode of Tongchuan has been chosen through optimizing leading industries--- potential exploration and strengthening. It can be included as harmonious pushing mode combining with the thoughts of development of Tongchuan, 5523, created in its practice. In the past few years, Tongchaun took a scientific and harmonious way for its social and economic development by carrying out the strategies of project-leading, industry-strengthened, sustainable development to form a cycle economic chain of coal mining, electric power, aluminum melting, and cement production. Meanwhile it also speeded up the development of industrial group and construction of industrial zones.To fulfill economic transformation and sustainable development of resource-based cities, it is necessary not only to choose a scientific development strategy and mode of transformation but to receive national policy supports in resources, finance, tax and industries, as well as setting up relative organizations in charge.The transformation of resource-based cities is a world-concerned issue and system engineering. This article focuses on transformation strategy and the selection of leading industries, less on effects and evaluation of social and environmental factors in the process of transformation, which needs further research.
