摘要:

目的 “两山”理论是为寻求生态环境与经济发展协同并进，实现“绿水青山就是金山银山”的生态发展理念。方法 为检验“两山”理论的实施效果，文章以国家生态文明试验区——海南省为例，运用包含非期望产出的超效率SBM模型测度农业碳排放效率，并利用耦合协调度和地理探测器分析海南省农业碳排放效率与农业经济增长耦合协调时空变化特征及驱动因素。结果 （1）2010—2021年海南省农业碳排放效率均处于非效率状态，效率值呈稳步上升态势，在市县层面上，农业碳排放效率均值最高的是三亚市，最低的是海口市；（2）研究期内海南省农业碳排放效率与农业经济增长耦合协调度呈现波动状态，其中，西部和中部市县耦合协调水平较低，东部市县的耦合协调水平较高；（3）海南省农业碳排放效率与农业经济增长耦合协调区域差异受到政府投入、教育水平、产业结构、能源利用、生活水平和城镇化等因素的共同作用。结论 海南省农业碳排放效率总体处于上升态势，多数市县农业碳排放效率与农业经济增长呈协调状态。

Abstract:

The “Two Mountains” theory aims to seek coordinated development of ecological environment and economic growth and realize the ecological development concept of “green mountains and clear waters are as valuable as mountains of gold and silver”. In order to test the implementation effect of the “Two Mountains” theory, this study took the national ecological civilization experimental zone, Hainan province, as an example, and used the super-efficient SBM model with non-expected output to measure the efficiency of agricultural carbon emission, and used the coupling coordination degree and geographic detector to analyze the spatiotemporal variation characteristics and driving factors of coupled coordination between agricultural carbon emission efficiency and agricultural economic growth in Hainan province. The study were showed as follows. (1) The agricultural carbon emission efficiency in Hainan province from 2010 to 2021 was in a non-efficient state, and the efficiency value was steadily increasing. And at the city and county level, the highest agricultural carbon emission efficiency mean value was in Sanya city, and the lowest was in Haikou city. (2) The coupling coordination degree of agricultural carbon emission efficiency and agricultural economic growth in Hainan province during the study period showed a fluctuating state, among which, the coupling coordination level of the western and central cities and counties was low, and the coupling and coordination level of eastern cities and counties was high. (3) The regional differences of coupling and coordination of agricultural carbon emission efficiency and agricultural economic growth in Hainan province were influenced by the combination of government input, education level, industrial structure, energy use, living standard and urbanization. In summary, the overall agricultural carbon emission efficiency of Hainan province is on the rise, and most cities and counties have harmonized their agricultural carbon emission efficiency with agricultural economic growth.
