Positive Research On The Development Of Nanjing's Satellite Cities

There are many academic fruits of the development of the City Clusters on Yangtze River Delta. It is few productions in studying the development of Nanjing's satellite cities as the system of "zonary cities". In 2004, the cities' governments of the City Clusters on Yangtze River Delta had extended the boundary of developing stratagems to "extensive Yangtze River Delta. Thus, this requires rebuilding the radiant and competitive force of central cities─Nanjing─ in urban agglomeration and reappraising the structure and situation of satellite cities in the city clusters, impelling the economy and society development of whole region in the eleventh five-year plan. First, "the quality of cities" was confirmed with symbolic methods, the mutual force between cities and radiant scope of a city were obtained, double meaning of "the quality of cities" based on the fruits of pre-scholar was expounded, the economic index of synthetic economic force of cities was established. Secondly, the principal component analysis has been used in this study. The procedure as follows: Step one, data were collected in order to create the economic index of synthetic economic force of cities. Step two, the quality of the cities being chosen was measured in order to analyze their development of economy with the principal component analysis. The formula of breaking points was used to research the radiant scopes of cities. Step three, the formula of gravitation was amended and model of log-linear gravitation was erected. Lastly, theoretic analysis and positive research were combined. Policy and advice were brought forward on the basis of three primary problems and three conditional factors which existed in the cities being chosen. The conclusion of this paper has considered some cases of other satellite cities to some extent. There were valuable references available to other ones.
