摘要

With the accelerating process of urbanization in China, the government's investment in urban infrastructure is increasing year by year. The problem of reckless investment, over-investment and unbalanced regional development have emerged while increasing the scale of investment. From the perspective of time evolution, this paper analyzes the total factor productivity (TFP) index, technological progress (TP) index and efficiency change (EC) index of infrastructure investment efficiency in 31 provinces in China from 2008 to 2015. The analysis shows that the investment efficiency of infrastructure fluctuating slightly in 2008 to 2015. The change of TFP in 2008-2010 is mainly affected by the change of technological progress. The change of TFP in 2010-2015 is mainly affected by the change of overall efficiency, and there is a certain degree of substitution effect between technological progress and technical efficiency. From the cumulative effect, the efficiency of Chinese infrastructure investment is declining. From the regional distribution, The TFP growth of the three major regions in China shows the rising trend of central, western and eastern of China. The change of technological progress is the same as that of TFP in the central region, and the efficiency of infrastructure investment shows little difference in the western regions. The TFP of infrastructure is mainly affected by technological progress in the eastern regions. This paper helps to improve the decision-making process of investment which in infrastructure projects with limited funds and the management level of infrastructure construction projects.
