Research On Problems Of Regional Economic Sustainable Development In The Vision Of Progress Of Economic Development Stages

Sustainable development is a common land problem which is related to whole human beings. As a core problem of sustainable development, economic sustainable development is for long a quarrel or game focus among countries, especially between developed countries and developing ones. Frequently, economic development and sustainability are a couple of contradictions and economic development can easily run fast if sustainability is neglected, therefore, some developing countries or regions whose most important task is developing economy, often only catch sight of immediate interests and neglect sustainable development problems which are characteristic with external non-economy, while developed countries or regions who have experienced fast economic growth have reached high economic level, frequently attach importance to sustainability. In fact, although economic sustainability is of external non-economy, once a sustainable development problem indeed appears, the first and the most serious harm will fall upon the local country or region. Take pollution as an example, wherever pollution is created, it will firstly and seriously harm the local inhabitants and their descendents. Moreover, sustainable problem is often irreversible and if it delays being handled, it can't be handled or must be paid much more cost than at beginning. Therefore, as responsible managers or constructors of regional economy, they must take a broad and long-term view, stick to sustainable development theory and draw up appropriate regional economic development strategy which orients towards economic growth of sustainability, cleanness, efficiency, friendly environments, resource-saving, and fairness between and within generations.However, in the past, people have only reached uniform recognition on connotation, idea and development principles of regional economic sustainability. On this basis, the paper researches and explores further on path dependent and criteria of regional economic development. The paper holds that regional economic sustainable development is characteristic with region and stage. To realize the aim of regional economic sustainable development, it is not required that the whole world, the whole country, or every region within a bigger region develop economy abiding by the absolutely uniform sustainable development standards, but it is required that every component region develop economy locally and gradually according to the region's economic development stages, regional economic development level, and regional economic features. The paper starts from related theories of regional economic sustainable development, put forward a theory that economic development stages determine the paths of regional economic sustainable development, and further discusses their function mechanism and process in economic lasting growth, economic development ways, regional equilibrium and ecological environment quality. Then Jiangsu economy is analysed empirically to discover its economic sustainable development problems. Finally Jiangsu economic sustainable development pathes dependent are suggested according to Jiangsu economic development stages.The research's biggest innovation lies in that regional economic sustainable development problem is researched in the vision of economic development stages and put forward regional economic sustainable development path matching economic development stages, that is, corresponding to economic development stages, deciding regional economy's leading industry type, economic development model, equilibrium development method, environment conservation method, and so on, which reflects developing countries' reality economic demand and enhances the practical directing function of the regional economic sustainable development theory.Research methods include combining dynamic analysis with static analysis, quantitative analysis with qualitative analysis, theoretical analysis with empirical analysis, as well as comparative method, mathematic model method, index method, game model method, and so on. Main conclusions of the research:(1) Regional economic sustainable development is a problem related to region and stage, and in correspond to regional economic features and regional economic development stages, it is also characteristic with features of non-equilibrium and historical marks. So it should be planned by combining with certain region's economic features and its economic development stage.(2) Economic development stages have inner links with regional economic sustainable development. Economic development stages decide regional economic development tasks, economic development level, technology level, environmental and ecological norm, and so on. Therefore, starting from economic development stages, there is a regional economic sustainable development path which matches regional economic development stages, economic continuous growth, intensive growth, regional balance and pollution handle being four key problems on this path.(3) The judgement of regional economic development stages may vary with different criteria. Every economic development stage matches certain economic tasks and responding industry types, but when regional economy is on one certain stage, its industries frequently don't all belong to the stage, but belong to different stages. The degree and variable trend of combined industries which belong to different stages reflects the evolution process of economic development stage.(4) According to Four Stages division method, Jiangsu is at industrialized later period. According to fuzzy comprehensive evaluation method, South Jiangsu, Middle Jiangsu and North Jiangsu are at post-industrialized period, industrialized later period and middle-stage industrialization respectively. In order to guarantee lasting growth of Jiangsu economy, Analytic Hierarchy Process should be utilized to choose leading industries and put them in order in South Jiangsu, Middle Jiangsu and North Jiangsu.(5) Intensive economy and extensive economy are relative and they keep changing and are integrated into the process of economic development. Generally, at lower economic development stage, there exists more degree of extensive economy and less degree of intensive economy. But at higher economic development stage, there exists less degree of extensive economy and more degree of intensive economy. Short-term extensive economy can help accumulate capital and develop advanced technology, which are the basis of intensive economy, so short-term extensive growth is also a part of economic sustainable development.(6) In order to attain the overall objective of Jiangsu economic sustainable development, it is necessary to narrow regional economic development gap, so economic investment or resource allocation among South Jiangsu, Middle Jiangsu and North Jiangsu should be regulated once again. Investment scale and direction should be regulated and optimized in terms of three regions' economic development stages and economic development features. At present, investment growth rate on Middle Jiangsu and North Jiangsu should be bigger than on South Jiangsu, which is beneficial to maintain the momentum of Middle Jiangsu and North Jiangsu's catching up with South Jiangsu.(7) In order to attain the ideal game result of "making enterprises handle pollution voluntarily, government need know about the cost enterprises, have to pay for handling pollution, offer appropriate assistance fund to enterprises, cut down check cost, check enterprises'deeds of handling pollution, and lay down pollution fine high enough.
