Wan Jiang City Belt Based On DEA-ESDA Urban Efficiency Evaluation

City as a regional social, economic and cultural center, is an important growth pole of regional and even national economic and social development.Since entering the new century, our country’s urban development and made great achievements, with the accelerating urbanization, the growing scale and sustained economic growth.Many, however, the current urban development efficiency is generally low, relatively extensive urban development model, "" high consumption, high pollution and low output of the phenomenon is more obvious, lead to a large amount of resource consumption, also reduces the quality of the development of the city.The development of the city should be high efficiency as the goal, only improve the efficiency of the city to improve the quality of the urban development, to promote the efficiency of city is to realize the city "sound and rapid development of the necessary way.C ity efficiency gradually, therefore, GDP and urbanization rate and urban economic scale, become the important indicators of urban development level, aroused wide attention from all walks of life.Based on wan jiang city belt 10 each prefecture(9) after 2011 as research samples, choose whole social fixed assets investment, urban construction land area, total power consumption, the whole society from personnel of course of whole society, postal telecommunications business as input indicators, choose region GDP, fiscal revenue as output indicators, DEA model is set up the evaluation index system.First 2007-2013 using the traditional DEA model to evaluate the efficiency of wan jiang city belt cities, find the merits of the traditional DEA can’t distinguish between effective unit, thus introducing virtua l evaluate the traditional CCR model of decision making units, input redundancy analysis was carried on.Secondly using DEA model of cross efficiency analysis of wan jiang city belt cities, with more obvious distinction between the pros and cons of different decision unit.Finally, using the ESDA exploratory spatial data analysis to study the evolution process of wan jiang city belt city efficiency and space differences.To cross efficiency value, per capita GDP, as measure index of investment in fixed assets, etc, the efficiency and economic differences of wan jiang city belt city comparative measure.The following conclusions:(1) efficiency in wan jiang city belt cities is generally not high, and presents the trend of the development of the wave type, GDP and fixed asset investment and belt cities shows a tendency of increasing year by year, and increase larger extent.(2) from the point of city type, lower efficiency than traditional industrial and mining city city comprehensive city;In the context of city scale, city scale efficiency and city has certain relevance, but the significance is not strong.(3) the location condition, policy and planning factor, spatial proximity effect, human capital, industrial structure, history and basic wan jiang city belt is main aspect of efficiency difference of l7 cities.Finally, combined with the actual situation of wan jiang city belt cities, from the regional cooperation, urban system construction, put forward the corresponding suggestion to the rational flow of population, to improve the efficiency of the belt citys.
