Land Use Efficiency Research On Urban Agglomeration In The Middle Reaches Of The Yangtze River

Urban agglomeration in the Middle Reaches of the Yangtze River is a large city group including the Wuhan city circle, Jing Xing Yi city belt, Chang Zhu Tan City Circle and Poyang Lake City circle. Urban agglomeration in the Middle Reaches of the Yangtze River is an important part of the Yangtze River economic belt, but also the central region for the implementation strategy. It is also the key areas to promote the comprehensive deepening reform and opening new urbanization. It plays an important role in the pattern of development in our region. Urban land is the cornerstone of the city’s economic and social and cultural development. Land resources are scarce, with the spatial expansion and urban industrial layout adjustment will cause further increase in demand for land. However, with the acceleration of urbanization process in China, the development of urban land issues have become increasingly prominent. Urban land use efficiency is low at the present stage of our country, and the waste issues are also outstanding. To ease the process of urban development of land conflicts, so that land use patterns and achieve economic growth mode from extensive to intensive type of fundamental change, the city must be intensive and economical use of available land and increase efficiency.This paper, based on large number of theoretical research and data analysis of the urban agglomeration in the Middle Reaches of the Yangtze River, elaborate related concepts and theoretical foundation. It gives an objective analysis of the urban agglomeration in the Middle Reaches of the Yangtze River land use, reveals land use characteristics from investment and output, and identify the problems of urban land use issues. This paper use DEA model to evaluation the Yangtze River city group land use efficiency based statistical data in 2006-2013 of the 28 cities in the urban agglomeration in the Middle Reaches of the Yangtze River. It select land input, labor input, capital investment and population density as the input indicator, and select economic and social benefits as the output indicator. Then use panel data model to analysis the relationship between land use efficiency and indicators.The main conclusions are as follows:(1) the higher the GDP and government receipts, the higher the land use efficiency. So in the future, we should set the GDP and government receipts as the important indicators in the land use plan. (2)the land supply increase makes the land use efficiency get down. In the development of city, we should control the amounts of land supply. (3) Investment in fixed assets increase make the land use efficiency gets down. We should transform the way of economy development, reducing the land supply scale which develops by increasing the investment in fixed assets.
