Under The Specialized Division Of Labor Angle Of View The Urban Cluster Evolution Mechanism Initially Searches

The paper takes division of labor theory as a foundation, uses method which the theory and the real diagnosis unify, key to the specialized division of labor and the urban cluster evolution general theory, the division of labor deepening promotion urban cluster crosswise expansion, the division of labor deepening promotion urban cluster longitudinal evolution these three aspect question has carried on the theoretical analysis, and in the theoretical analysis foundation, has carried on the brief analysis to our country urban cluster development.The main research conclusion is as follows:(1) Between specialized division of labor and the urban cluster evolution is affected mutually: The specialized division of labor promotion urban cluster development evolution, the division of labor deepening is the urban cluster development evolution basic power; In turn, the urban cluster development is advantageous to the knowledge accumulation and the technological innovation, the knowledge accumulation and the technological innovation degree are deciding the division of labor deepened degree, simultaneously is also affecting the urban cluster development evolution level.(2) urban cluster boundary is by the urban cluster in between various cities the transaction marginal expense and the marginal revenue decision, the two have equally decided the urban cluster most superior scale; In fact the urban cluster boundary is fuzzy, dynamic, which don't necessarily happen at this point, but as a result of market function is general meeting in this place which can be contracting or expanding at this place. (3) division of labor deepening promotion urban cluster crosswise expansion: As a result of dividing the work forms the different knowledge accumulation and the specialized skill, gathers in some city region, causes in the urban cluster various cities to form mutually the different relation relations specialized market, longitudinal necessary and so on the different urban cluster type; The division of labor further deepening promotes urban cluster longitudinal evolution, in functions such as under knowledge accumulation and technological innovation, organization innovation, which causes the urban cluster experience to the form, the development and the mature stage, various stages have its different characteristic.(4) our country's urban cluster development experienced for several dozens years have begin to take shape, but have many problems, between in which urban cluster interior various cities locating is not clear, the specialized division of labor is not obvious, between the city border transportation facility is backward, creates between the city to relate not closely, which is the primary cause restricts the urban cluster development; Between the enhancement urban cluster interior various cities division of labor and cooperation, speeding up between the city border the transportation communication facility construction, reducing the transaction expense, which are one of main ways promoting our country urban cluster development.
