Abstract:

The article selects 3 large index systems such as competitiveness of resources product, market service as well as tourism security, and uses entropy method to give weight to the 3 big index systems so as to measure urban tourism competitive potential of the Changjiang River Delta horizontally. Combined with SSM model, this article calculates longitudinally the structure deviation component and competitiveness deviation component of urban tourism competitive potential index factors from 1998 to 2008. At the same time, the structure effect and the competitiveness effect of index factors are evaluated on the basis of longitudinal calculation. The results show that there are significant differences in the temporal patterns of urban tourism competitive potential of the Changjiang River Delta. The urban tourism competitive potentials of 4 central cities including Shanghai, Nanjing, Hangzhou and Suzhou are higher, which form the spatial pattern of 4 culminations. Moreover, the difference of urban tourism competitive potential displays the expanding trend. However, it occurs that there is unreasonable situation of the structure of index factors, which does not match entirely with the corresponding tourism competitive potential. Specifically, the whole competitiveness of market, service, traffic carrying capacity and economic development support of Shanghai is very strong. On one hand, the basis of image competitiveness is better while the competitive potential has the decreasing trend. On the other hand, the basis of resources competitiveness is better while the state begins to decline. The significant characteristics of Hangzhou City are that the competitiveness of image and product has the good development, which has the better basis and the large competitive potential. For Nanjing, its competitiveness of market, resources and product has the better basis and its status advances distinctively while other indexes appear the declining trend. The competitiveness of image and service of Suzhou City develops rapidly and has the prominent advantageous position. Therefore, through the two clear contrasts between the horizontal aspects and the longitudinal aspects, the weaknesses and defects of the different urban tourism competitive potential indexes are reflected and the performance of the different urban tourism competitive potential is shown objectively and accurately. As a result, the article provides the quantitative basis and the theoretical reference for advancing the different urban tourism competitive potential of the Changjiang River Delta.
