A Study On The Transformation And Promotion Of Zhejiang 's County Economy To Urban Economy

County economy is the achievement of rural marketizaition reform. The interaction between urbanization focused on towns and rural industrialization promotes county economy to develop rapidly. After entering the new century, some limitations such as low industrial level, small company scale and scattered spatial layout force county economy to change. At present, Zhengjiang’s GDP per capita has been more than 10000 dollars,which means Zhejiang has entered the late stage of industrialization when urban economic is dominating Zhejiang’s economy. In fact, urban economic with a tertiary industry and network-spatial layout is agglomeration economies,having a stronger radioactive effect and agglomeration effect. Compared with county economy, urban economic is intensive with a higher industry level and agglomeration degree. So, whether it is actual needs of the county economy, or the inherent requirements of Zhejiang’s economic transition,we require county economy to upgrade. With the urbanization, marketization, and industrialization, Zhengjiang’s county economy is upgrading to urban economic.This paper has four conclusions. First, county economy transiting to urban economic is to deepen specialization in essence. It is an economic form change,including industrial structure from industrialization to servitization, spatial layout from one center to several centers, regional function from produce to service. It is not an adjustment of administrative division and not a vanishing of county economy. Secondly, county’s inner specialization can promote industrial structure to change,and then the county’s transition. Regional specialization can strengthen key cities, and then urban economic leads county economy to change. Thirdly, the most important thing for county economy’s upgrading is to find out specialization promotion mechanism that is urbanization, industrialization, and marketization. Because transaction costs, production coordination costs, market scale and other factors influence specialization level. Fourthly, the general idea for Zhejiang’s county economy upgrading to urban economic is deepen specialization and interact ‘stronger county strategy’ whose main force is county urbanization and ‘Metropolitan Region strategy’ whose main force is the new urbanization. While urbanization, industrialization, and marketization are still functioning, informatization should also be emphasized to promote Zhejiang’s industrial agglomeration and improve the professional markets.This paper has two innovations.First,the topic is newer. Secondly,it is the first time to discuss the issue on county economy transiting to urban economic systematically. It is not just an experience-based judgment. However, there are also two shortcomings. First, research on county-economy’s transition conditions is not enough. If we are able to calculate specialization level, then we can know when it is the best time for county-economy to transit. Secondly, research on metropolitan-area’s central city is not enough. If we can use Social Network Analysis, then we can do Centrality Analysis and Core-Periphery Structure Analysis. So we are able to find out the region’s central city. And we can promote county economy to transit by improving central-city’s energy level.
