ECO-EFFICIENCY MEASUREMENT AND INFLUENCING FACTORS ANALYSIS ON PEARL RIVER DELTA URBAN AGGLOMERATIONS IN CHINA

摘要

Based on the panel statistic of 9 cities of Pearl River Delta (PRD) urban agglomerations from 2006 to 2016 in China, the super efficiency model (SBM) and Malmquist index have been used to measure the static and dynamic eco-efficiency on PRD urban agglomerations. With the Tobit analysis method, this paper studies the influence factors of eco-efficiency upon PRD urban agglomerations. It can be found that, there is a steady upward trend on the static eco-efficiency of 9 cities PRD urban agglomerations during 2006-2016. Most of the loss of comprehensive technical eco-efficiency is chiefly resulted from the scale efficiency. The dynamic eco-efficiency of PRD urban agglomerations has been improved by technological progress. The loss of eco-efficiency can be compensated by technological advancement. Density of population, per capita annual income, education degree and ecological protection policy all have positive correlation with influence upon the eco-efficiency of PRD urban agglomeration. The proportion of secondary industry output to GDP has the great inhibitory effect on environmental efficiency. The implementation of eco-environmental policies with public financial support can promote the improvement of urban eco-efficiency. It is necessary for the local government to implement a diversified performance measurement system that includes ecological protection policy assessment, to promote the coordinated development of urban economy and ecological environment from the legislative, law enforcement and supervision perspective.
