However, on the academic research level, the research of characteristic towns is lack of systematic. Under these circumstances, this article summarizes the current research on the characteristic town in our country, and makes relevant research and evaluation, with a view to providing reference and basis for further research on the characteristic town.展开更多

In this paper, comprehensive assessment indicators for re- gional economic development and environmental pollution subsystems are constructed. Then the degree of coupling and coordination of the regional economy-environment system is calculated for 350 prefectural units in China. It is found that the economic development and environmental pollution in most prefectural units is still at a low level of coupling and coordi- nation. According to the coupling and coordination values, the Chinese territory can be di- vided into four types of area: economy-environment harmonious area, economy-environ- ment gearing area, economy-environment rivaling area and low coupling degree of econ- omy-environment area. Based on a structural analysis of the industrial sector in the four types of areas, there is a spatial relationship between the regional industrial sector structure and the coupling-coordination level. In the economy-environment harmonious area, the sectors of manufacturing of high-technology and high value-added products, such as com- munications, computer and electronic equipment, transport equipment and electrical ma- chinery, account for a large proportion of the value of local industrial output. The industrial value of the economy-environment gearing area is concentrated on the manufacturing of machinery and equipment, and. contains a few polluting sectors such as ferrous and non-ferrous metallurgy, chemical manufacturing and electricity generation. The econ- omy-environment rivaling area is the type of area where polluting sectors concentrate, such as iron and steel, petrifaction, coal mining, building materials and electricity generation. In the low coupling degree of economy-environment area, its industry is concentrated on the pro- duction and processing of primary products.展开更多
