中国城市生态效率测定及其时空动态演变
Measurement and temporal-spatial dynamic evolution of urban eco-efficiency in China
摘要
Abstract
Based on the panel data of 285 prefecture level cities and above in China from 2003 to 2015,the super efficiency model (SBM) has been used to measure the urban eco-efficiency.Based on the time comparison analysis and spatial correlation analysis,the temporal-spatial evolution pattern of urban eco-efficiency has been analyzed by constructing traditional and spatial Markov chain transition probability matrix,and then this paper discusses its dynamic evolution characteristics.The results show that:① The urban eco-efficiency shows a gradual upward trend as a whole,and it has achieved some success through shifting to intensive mode during the time evolution process.The amount of cities with higher eco-efficiency in the central and western regions increased more than those in the eastern cities,which means that the urban eco-efficiency of central and western cities increased significantly,while the overall urban eco-efficiency of eastern cities decreased.② The global Moran's I index values are positive,which means the spatial distribution of urban eco-efficiency shows a significant positive correlation,and shows spatial clustering characteristic with significant neighbor effect.③This paper divides four adjacent but not intersect complete ranges based on the urban eco-efficiency.As the traditional Markov chain transition probability matrix shows that,the trend of urban eco-efficiency transferred to high level is remarkable,and its evolution had the stability to maintain with the original state,which is difficult to achieve the leap forward transfer.④ The spatial Markov chain transition probability matrix introduced into spatial lag shows that,the geographical location background has a significant effect on the temporal-spatial evolution of urban eco-efficiency,and has a fluctuating clustering phenomenon in spatial distribution.The influence of eco-efficiency among adjacent cities is mutual and presents an agglomeration pattern in space,and the higher eco-efficiency city drives the nearby cities to upward transfer more likely to have a positive spillover effect,showing a'club convergence'phenomenon of'high constant high,low still low,high drive low,low restraint high'.Finally,this paper also analyzes the shortcomings and direction of improvement in current research,and put forward relevant policy suggestions,including more stringent resource and environment policies,strengthening urban ecological cooperation and exchange,drawing on the experience of urban ecological environment management with higher eco-efficiency in neighboring cities and so on.关键词
