新常态下中国大城市绿色增长效率研究

Study on Greener Growth Efficiency of Large Cities in China in the New Normal State

为提升城市化进程下生态文明建设水平和绿色发展质量,研究城市绿色增长效率特征,基于全国46个最具代表性的大城市的经济产出、资源投入、环境排放3个子系统的指标,采用综合指标评价方法和多重对应分析方法,分析大城市在新常态下的绿色增长效率特征。结果表明:大城市绿色增长效率呈现东高西低、南高北低的格局,城市级别越高、人口规模越大,绿色增长效率越高;变化方面,重工业城市在新常态时期的绿色增长效率总体提升幅度较小,而西南、西北地区的城市分别在经济产出、资源投入、环境排放方面有较显著改善。基于分析结果,文中提出:在推动城市绿色发展的过程中,应针对发达大城市、区域中心城市、重工业依赖型城市等各类城市的发展特点,分别制定提高城市绿色增长效率战略,走差异化的绿色发展道路。

To improve the level of ecological civilization construction and the quality of green development under the process of urbanization, the characteristics of urban green growth efficiency were studied. Based on the indicators of economic output, resource input and environmental emission of the 46 most representative large cities in China, the synthetic index evaluation method and the multiple correspondence analysis methods were used to analyze the greener growth efficiency characteristics of large cities in the new normal state. The results showed that the efficiency of greener growth in large cities was higher in the east and lower in the west, and higher in the south and lower in the north. Cities of higher level or larger population scale tended to be more efficient in greener growth. In terms of changes, the greener growth efficiency of the heavy industry cities in the new normal period had a smaller overall increase, and the cities in the southwest and northwest China had significantly improved their economic output, resource input and environmental emission, respectively. Based on the analysis results, it was proposed that in the process of promoting the green development of cities, formulating strategies are necessary to improve the greener growth efficiency and take differentiated green development paths according to the development characteristics of various kinds of cities, such as developed large cities, regional central cities and heavy industries dependent cities.
