我国农业经济与生态系统耦合协调发展评价

Evaluation on the Coupling and Coordinated Development of Rural Economy and Ecosystem in China

探索我国农业经济与生态系统之间的耦合协调关系,可为农业经济的高质量发展与乡村振兴战略的实施提供有力支持。论文通过构建农业经济与生态系统综合评价体系,运用熵值法和耦合协调度模型计算2011—2020年我国31个省份的农业经济与生态系统综合指数,探究我国农业经济与生态系统的耦合协调演化规律,并根据研究结果给出相应建议。结果表明,2011—2020年间我国总体及各区域的耦合度均处于高度耦合阶段,但耦合协调度较低,处于濒临失调阶段。部分省份耦合协调度增幅较为明显,如北京、安徽、四川等省份已进入濒临失调阶段,江苏、山东与广东3省已进入初级协调阶段;但中西部地区多数省份仍处于中度失调或轻度失调阶段,缺乏优质的耦合协调省份。2020年,我国轻度失调与濒临失调省份较多,分别占比38.7%、32.3%,初级协调占比仅为9.66%。

Exploring the coupling and coordination relationship between China’s agricultural economy and ecosystem can provide strong support for the high-quality development of agricultural economy and the implementation of the strategy of rural revitalization.In this paper,by constructing the comprehensive evaluation system of agricultural economy and ecosystem,using entropy method and coupling coordination degree model to calculate the comprehensive index of agricultural economy and ecosystem of 31 provinces in China from 2011 to 2020,the coupling coordination evolution law of agricultural economy and ecosystem in China was explored,and corresponding suggestions were given based on the research results.The results show that from 2011 to 2020,the coupling degree in China as a whole and in all regions is in the high coupling stage,but the coupling coordination degree is low,which is on the brink of misalignment stage.For example,Beijing,Anhui,Sichuan and other provinces have entered the stage of near imbalance.Jiangsu,Shandong and Guangdong have entered the stage of primary coordination.However,most of the provinces in central and western China are still in the stage of moderate or mild imbalance and lack of high-quality coupling coordination.In 2020,there were more provinces with mild and near imbalance,accounting for 38.7%and 32.3%respectively,while the proportion of primary coordination was only 9.66%.
