中国县城市政工程全要素生产率研究

Research on Total Factor Productivity of Municipal Engineering of China’s County

基于DEA─Malmquist方法,利用2006~2018年中国县城市政建设的面板数据,对中国县城市政工程全要素生产率(TFP)进行测度。以测度结果为基础,分别从时间、空间以及增长模式三个角度,对市政工程基础设施效益进行分析与评价。结果表明:中国县城市政工程TFP总体呈下降趋势,且整体水平不高,正、负增长间断出现的特征比较明显;TFP下降主要受来自技术进步的影响,技术效率在样本期内有小幅度增长,规模效率下降是技术效率在增长过程中的主要负面因素;TFP水平空间差异性比较明显,各区域内部差异各有不同,华北、东北和西南地区内部差异要高于其他地区;TFP增长主要模式为"实践型"和"落后型",由技术进步引起的"拖累效应"比较明显。

Based on the DEA-Malmquist method,this paper measures the total factor productivity(TFP)of China’s county municipal construction by using the panel data of China’s county municipal construction from 2006 to 2018.Based on the measurement results,this paper analyzes and evaluates the benefits of municipal engineering infrastructure from three perspectives:time,space,and growth pattern.The results show that the TFP of China’s county municipal engineering is generally declining,and the overall level is not high,and the characteristics of positive and negative growth are obvious.The decrease of TFP was mainly due to the influence of technological progress.The technical efficiency increased slightly during the inspection period,and the decrease of scale efficiency was the main negative factor in the growth process of the technical efficiency.The spatial differences of TFP level were obvious,and the differences within different regions were different.The differences within North China,Northeast China,and Southwest China were higher than those in other regions.The main modes of TFP growth are"practice type"and"backward type",and the"drag effect"caused by technological progress is obvious.
