The Determination Of Urban Efficiency In China

Urban efficiency is a comprehensive concept. It produces undesirable output along with the desirable output. Just taking the desirable output into consideration will ignore the negative effects which brought by cities.Use the input and output data of262prefecture-lever cities from2004to2010and the slack based measure of data envelope analysis method, this paper analysis the efficiency of Chinese cities. The study finding that the Chinese city efficiency is smooth as a whole, the east district and the big cities own higher efficiency, the middle and west district together with the middle and small cities own lower efficiency. All district and scale cities efficiency will decrease in varying degrees if considering the undesirable output, the east district and the big cities decrease most.The efficiency gap among Chinese cities is being bigger, there doesn’t exist characteristic of convergence. The east and middle district together with big cities and middle cities either own amplifying or stand efficiency gap, there doesn’t exist characteristic of convergence.there exist the characteristic of convergence in west district, but the convergence will be missing if we take the undesirable output into accout.The small cities’ efficiency gap is being narrow, there exist convergence among small cities whether we take the undesirable output into account or not.Through using the tobit model to analysis the influence elements we find that spatial agglomeration and scale of cities has a positive and remarkable influence to the efficiency of Chinese cities, it mainly existed in east district and big cities; the open degree also has a positive and remarkable influence, but it will be not remarkable when we considering the undesirable output; the percent of fixed investment has a negative and remarkable influence to the efficiency in both conditions, Chinese cities has a low fixed investment efficiency or degree; the percent of government expenditures has no remarkable influence to the efficiency, but it will changed into been positive and remarkable influence when it takes the undesirable output into consideration, the percent of government expenditures influence to the city efficiency in east district and big cities always be positive and remarkable; the location conditions has a positive and remarkable influence, east cities has a higher efficiency, but it will be no remarkable influence when we take the undesirable output into consideration.We raise the following policy suggestion according to the above demonstration results. Develop the east district and big cities first together with reducing the undesirable output; improve the cities spatial agglomeration, especially the east district and big cities; control the population agglomeration; adjust the structure of fixed investment and improve the efficiency of fixed investment.
