The Study On Economic Spatial Pattern Of He-Wu-Beng And Its’ Optimization

The economic spatial pattern is the epitome of economic activities on region. In different process of economic development, the economic spatial pattern has different features. Analyzing the regular pattern of economic spatial pattern evolvement, and grasping it’s changing trend is very useful to plan economic space layout and achieve the efficient allocation of resources. As an important axis of Anhui Province, the reasonable layout of economic spatial structure of He-Wu-Beng is not only can improve the whole regional economic strength, but also can play a direct role in promoting economic of Anhui to develop orderly.On the base of he full understanding and absorbing the existing research and basic theory, this paper uses many methods to analysis the economic spatial pattern of He-Wu-Beng from multiple profiles and multiple angles. First of all, this paper uses revised gravity model to analye Hefei-Wuhu-Bengbu spatial economic relations from macro-level. Based on that, we analyses the spatio-temporal of evolution of population, economic development level and economic growth type of He-Wu-Beng. In the same time, we select urban density, economic development level, urbanization rate, traffic density, central city indexs, variation coefficient of economic disparity and fractal dimension of regional space to evaluate whole coordination level of He-Wu-Beng, and point the main problems currently. At last, we put forward the targets and strategies of He-Wu-Beng economic spatial pattern optimization in short-term and long-term. This paper’s research results include following aspects:(1) There are strong interaction and obvious economic impact in the three cites.(2) In He-Wu-Beng, the agglomeration economy level is not high, and population distribution appear to unbalance situation. So urgent task is to accelerate the city economic development, and improve agglomeration economic level.(3) The whole coordination level of He-Wu-Beng is more and more better, but it still belong to uncoordinated. This paper take low agglomeration population level, the shortage of center city driving force, the large economic gap and the shortage of spatial plan as the main problems,(4) The optimization objection in He-Wu-Beng is to form the shape of "circle" in short-term and "井"in long-term.
