Abstract:

 For the evaluating index system of the city' s comprehensive competitiveness in the Yangtze River delta, what we should consider is not only the city' s competitiveness but also the city's ability to accumulation and diffusion in the city group, that is to say, considering comprehensively the internal and external factors of influencing the city' s comprehensive competitiveness. The internal factors include comprehensive competitiveness, infrastructure levels and social harmony. And the external factors include the sharing degree of intercity infrastructure and the division of work and cooperation between cities. This essay, by way of factor analysis, makes an evaluation of the comprehensive competitiveness of the 25 cities in the Yangtze River delta. The conclusion is as follows: while the city' s comprehensive competitiveness of such 9 cities as Shanghai, Suzhou, Nanjing, Hangzhou, Wuxi, Ningbo, Changzhou, Shaoxing and Jiaxing is above the average level in the Yangtze River delta, the city' s comprehensive competitiveness of other cities is below the average level in the Yangtze River delta. By a cluster analysis, these 25 cities can be divided into five categories. While the cities of the same category are close to each other in development, there is a distinct difference in development between the cities of the different category. And there is also a very close relationship between intercity collaboration and the city's comprehensive competitiveness. On the one hand, viewing from the evaluation of the city' s competitiveness, the degree of collaboration and the level of collaboration between different cities plays an important part in the city's comprehensive competitiveness; and, on the other hand, viewing from the strategy of different cities to enhance comprehensive competitiveness, although the strategy itself vary due to differences in their conditions, its internal demand for collaboration is common. Therefore, any city' s enhancement in the comprehensive competitiveness is inseparable from the full collaboration of its related cities.
