| The coordinated development of Beijing-Tianjin-Hebei region is a national development strategy,and the coordinated development of ecological environment is the main theme of the coordinated development of Beijing-Tianjin-Hebei region.The problem of water resources is one of the most concerned problems in the current ecological environment.Because of the complexity of our country’s economic form,the problem of water resources presents diversification and complexity.At present,the coordinated governance of water resources in Beijing-Tianjin-Hebei region has achieved good results on the whole,but also faces greater challenges.Based on the present situation of water resources in Beijing-Tianjin-Hebei region,this paper constructs a comprehensive evaluation index of water resources.Then,taking economic development level,industrial structure,urbanization level,population density,import and export level,wage level,sunshine duration,average temperature,average relative humidity and average precipitation as control variables,the synthetic control model is constructed by using the panel data of 31 provincial administrative regions from 2003 to 2020.Finally,the policy effect of Beijing-Tianjin-Hebei ecological synergistic governance on the comprehensive benefits of water resources in this area was evaluated with this model.It is found that the comprehensive benefits of water resources in Beijing,Tianjin and Hebei have improved to some extent,but the governance effect of Hebei Province has a time lag.On the basis of the above research,this paper,based on the panel data of the BeijingTianjin-Hebei region from 2015 to 2020,further explores the driving forces of technical factors,governance willingness,economic strength and population on the effectiveness of water resources governance by using the logarithmic mean Divisia Index Method(LMDI).The results show that technological factors and investment willingness are the main driving factors,economic strength is the secondary driving factor,and population is not the driving factor.At the same time,it is found that the driving factors of each year in Beijing,Tianjin and Hebei have significant heterogeneity,which is manifested in the following aspects:Beijing has entered the efficient governance stage of using scientific and technological innovation for effective governance;Tianjin is in the period of reducing costs and increasing efficiency mainly from capital to technical innovation;Hebei Province is in the subcoordination stage,and although the governance effect is better at the present stage,the technological innovation is falling behind gradually and can not keep up with the demand of water resources governance. |
