Research On Tourism Economic Regional Differences And Mechanism Of Urban Agglomeration In The Middle Reaches Of The Yangtze River

In the development background of economic globalization and regional economic integration, urban agglomerations will inevitably become the subject of regional economic development. A favorite of the national policy, Yangtze River Delta urban agglomerations occupies an important place in the pattern of regional development in our country. To Promote the development of urban agglomeration in the Yangtze River Delta urban agglomerations is of great significance to accelerate the rise of central region strategy, explore a new path of urbanization and promote the development of regional integration. Integration of tourism is an important aspects to achieve the integration of urban agglomeration in the Yangtze River Delta urban agglomerations.As so many enhancements made to the exchanges and cooperation of regional tourism, tourism economic ties of the Yangtze River Delta urban agglomerations will become to be closer. In recent years, tourism industry has gained adequate development, facing an increasing scope and pressing problems calling for solution.The expansion of the tourism economic differences and spatial differentiation of two levels are outstanding problems. These problems have seriously restricted the new development of regional economy and tourism industrial integration. Therefore,building reasonable economic network structure is an important content to realize the coordinated development of regional economy, it is also the urgent requirement of integration of urban agglomeration in the construction of Yangtze River Delta urban agglomerations.Taking 26 cities of urban agglomeration in the middle reaches of the Yangtze River as the research objects, The article firstly constructs tourism economy network by calculating the tourism economy connection between two destinations, then it analyze the tourism economy regional disparities from the perspective of time and space evolution, the conclusions are as follows:(1) From 2002 to 2012, the network characteristic results indicate that the performances of tourism economy network structure is optimized of urban agglomeration in the middle reach of Yangtze river, the relationship of tourism economy between cities are strengthened,but overall, it is still in a state of weak ties.(2) The article uses the local spatial autocorrelation to study the tourism economic differences of urban agglomeration in the middle reach of Yangtze river,and find that it is still in a non-balanced development phase, and the absolute difference is increasing; tourism economic development of county(city, area) domain exists significant global spatial autocorrelation in the space layout, and presents obvious core-edge structure. Marginalized characteristics and club convergence coexist.(3) A reasonable network structure of tourism economy can well display their respective advantages in competition of regional tourism development and stimulate one another for common development.According to the research conclusion, the tourism economic integration development strategies are proposed in three aspects from cultivating space important node, strengthening regional tourism cooperation, constructing the system of tourism development.
