A Study on the Coupling Coordination Degree and Temporal and Spatial Evolution of China's Agricultural Green Development Level and Agricultural Science and Technology Innovation Capability

绿色发展是生态文明建设的必然要求,而科技创新则是破解绿色发展难题的关键所在,为了实现农业高质量发展,提高农业绿色发展水平,本构建农业绿色发展水平与农业科技创新能力评价指标体系,运用熵值法测算农业绿色发展水平和农业科技创新能力综合水平,并通过耦合协调度模型对农业绿色发展水平和农业科技创新能力综合水平进行耦合协调度测算,并运用核密度估计法、标准差椭圆、空间马尔科夫链等方法,分析农业绿色发展水平与农业科技创新能力综合水平耦合协调度的时空演变特征。研究表明:中国农业绿色发展与科技创新的耦合协调水平持续提升,尽管地区间存在差异,但整体上各省份在农业绿色发展与科技创新的融合方面取得了积极进展。耦合协调度在空间分布上大体呈梯形分布,反映了经济发展水平、科技创新能力与农业绿色技术推广和应用之间紧密联系。同时,耦合协调度的空间状态转移具有较高的稳定性。因此要加大对农业绿色发展的科技支撑力度,着力突破农业科技成果转化难题,建立跨区域、跨部门的农业科技创新协同发展机制。

Green development is an inevitable requirement for the construction of an ecological civilisation,while scientific and technological innovation is the key to solving the problems of green development,in order to achieve high-quality development of agriculture and improve the level of green development of agriculture.An evaluation index system was developed the level of accessing green agricultural development and the capacity of agricultural science and technology innovation.The Entropy Method was used to determine the comprehensive level of the two systems.The coupling coordination degree of the dual system's comprehensive level was evaluated using the CCDM(coupling coordination degree model).KDE(kernel density estimation),Standard Deviational Ellipse,Spatial Markov Chain,and other methods were used to analyze the spatiotemporal evolution characteristics of the coupling coordination degree between agricultural green development level and agricultural innovation ability.The research findings indicated that the overall level of coupling coordination between China's dual systems was increase.Among them,the eastern region experienced the most significant increase,followed by the central region,and lastly the western region.The coordination degree of China's dual system coupling exhibited a pattern of'high-high aggregation,low-low aggregation'evolution.The overall level of spatial agglomeration in China's dual system coupling coordination showed a rising tendency,with high-level development areas exerting spatial correlation effects on medium to low development areas.Therefore,it is necessary to strengthen the scientific and technological support for the green development of agriculture;endeavour to break through the difficulties in the transformation of agricultural scientific and technological achievements;and establish a cross-regional and cross-sectoral mechanism for the collaborative development of agricultural scientific and technological innovation.
