Abstract:In order to deeply explore the driving factors of urbanization on ecosystem service value and the spatial spillover effect of ecosystem service, taking the county of Shanxi Province as the research unit, based on the land use data and socio-economic data from 2000 to 2018, constructs a comprehensive evaluation system of ecosystem service value and urbanization level, and analyzes the spatial characteristics of the correlation between urbanization and ecosystem service value through bivariate spatial autocorrelation, In addition, the spatial econometric model is used to explore the driving factors of urbanization on ecosystem service value and the spatial spillover effect of ecosystem service. The results showed that: During the study period, the ecosystem service value of Shanxi Province showed a downward trend as a whole, and the comprehensive level of urbanization was significantly improved, but the overall level was low. There is a significant negative correlation between urbanization and ecosystem service value in the study area, showing a U-shaped development trend. The results of spatial econometric model show that the urbanization rate, built-up area and ecosystem services are significantly negatively correlated, while the per capita retail sales of social consumer goods and the square of urbanization level are significantly positively correlated with ecosystem services. Ecosystem service value has a positive spillover effect on neighboring counties. Under the premise of controlling other explanatory variables unchanged, every 1% increase in the ecological value of neighboring counties will have a 0.243% promotion effect on the county. Ecosystem services in the study area are integrated and unstable, which makes the county governments lose their enthusiasm for environmental protection.
