Research Of Enterprise Migration And Function Transformation In Central City

City plays a key role in the economic development in our country. In recent years, china is in a process of economics transformation, which requires the relevant functional shift of city. As the rationalization of industrial structure is closely related to the function of city, so its optimization and transformation appears to be very important. Especially in the central city, for its core position in economics and its regional attribute, it's more necessary to adjust the industrial layout, in order to promote the associated regional development. Enterprise migration shows the most direct effect towards to the industrial layout in central city, it helps to transform the industrial structure, as well as function re-built in a city.This article firstly analyses the relationship between enterprise migration and city industry transformation, which elicit the basic mode of enterprise migration dominated by the government, then under the background of changing the method of economic development, as well as a city industrial structure transformation in Zhejiang, it traces the process of enterprises, industry, government strategy, discover the actuality and how enterprise migration changes over time. The relationship between government and enterprise, the incentive mechanism are also problems to be researched on the basis of collecting micro data. First but not least, on the foundation of researching relevant files of Hangzhou enterprise migration, utilization ratio of city land, and territory occupation development, by quantifying the immigration of service enterprise and emigration of manufacturing enterprise in the city of Hangzhou, it reflects the insufficiency upon the earning and cost. What's more it discusses how to achieve the target of restricting pure economics interests, avoiding quantify deviation in stretagy,amending real effect of industry structure, for the purpose of promoting Hangzhou economics.Relationship between enterprise migration and city industry transformation in the economics evolution contains much theoretical meaning:first, Hangzhou is chosen to be the example city, combined with the enterprise migration and city industry transformation theories, is helpful to set stage for industry transformation analysis. At the mean time, it helps to broaden the vision of city economy research, giving necessary theoretical support for urbanization and industrial structure research. Second, the incentive mechanism between enterprise and government is also an emphasized topic in the article. Background factors are much more concerned compared with the former government-enterprise relation theory, which describes the development discipline of central city and regional industry, supplying advices in industry location and layout. Third, suggestions are also rendered for rationalization of government policy. When central city produces consequences for region, this region reversely promote the city economy. In the implement of policies, the function of city must be considered accordingly so as to integrate it to the competitive power.As economy centralization and diffusion ability of central city kept increasing, it's covering much larger area, with much closer connection to the economy in the surrounding areas. Upon this fact, this article contains rich realistic meaning:first, it's necessary to research the basic operation mode of both manufacturing enterprise and service enterprise, as well as the government-offered preferential policy in this procedure, which means much to the increasing of migration effectiveness. Second, as mentioned above, incentive mechanism between firms and government, including profit and cost, should be explored to make migration smooth. Third, contradiction and problems in the quantifying procedure is to be researched to find out the cause of the deviation. With reference to the case of Hangzhou, optimizing the operation stage, is what's needed to make benign in conformity with quantifying process in the micro economy, finally promoting migration effect, giving realistic reference for central city industry transformation,and finally achieve the goal of servicing the economy of Hangzhou and the country.
