Abstract: To explore the interaction between agricultural industrial integration and eco-environmental to realize economic growth and ecological improvement, and to advance industrial integration and eco-environmental co-integration, this paper analyzes agricultural industrial integration development and eco-environmental changes and their coupling coordination in Pengyang county from 2008 to 2022, based on vector regression model, pulse responsive function and variance decomposition to study the dynamic striking and mutual mechanism of agricultural industrial integration and eco-environment. Pengyang's agricultural industrial integration and eco-environment quality show a fluctuated rising trend during the study period. Two systems' coupling coordination has been increasing, starting at 0.364 in 2008, up to the highest at 0.804 in 2021. Three stages can be divided. Agricultural eco-environmental quality is higher than agriculture industrial integration level from 2008 to 2011; coupling coordination of the two systems is rising but still low from 2012 to 2017; coupling coordination of the two systems is rapidly rising from preliminary coordination to moderate coordination from 2018 to 2022. Pulse responsive value of agricultural industrial integration index to agricultural eco-environmental index is always positive, suggesting an acceleration on eco-environment. Dynamic striking response effect of agricultural industrial chain extension on eco-environment shows a first-rising-then-declining promotion; that of agricultural multi-functional extension and agricultural servicing integration on eco-environment shows an accelerating promotion, meaning that industrial integration can effectively promote rural eco-environment. Dynamic striking response effect of eco-environment on agricultural servicing is positive, but negative on agricultural industrial chain extension index and agricultural multi-functional extension index, suggesting a constraining role. Variance decomposition indicates that the average contribution rates of changes in agricultural industry chain extension, agricultural servicing integration and agricultural multi-functional extension to rural eco-environmental quality are 18.08%, 24.09% and 0.17%, respectively. The average contribution rate of rural eco-environmental quality itself reaches 57.66%.

摘要： 为了探究农村产业融合与生态环境的相互作用机理，实现经济发展和生态提升双赢，推进产业融合和生态环境协同发展，以宁夏彭阳县为例，分析了彭阳县2008—2022年农村产业融合发展水平和生态环境质量的变化以及两系统间耦合协调程度，在向量自回归模型的基础上，利用脉冲响应函数和方差分解法探究农村产业融合和生态环境的动态冲击效果和相互作用机理。研究表明：1）研究期内彭阳县农村产业融合水平和生态环境质量均表现出现波动上升态势，整体水平持续向好；2）两系统耦合协调度处于逐步提升过程中，由2008年的0.364逐年提升，最高在2021年达到0.804，过程大致分为3个阶段，2008—2011年农村生态环境质量优于农村产业融合发展水平，2012—2017年虽然两系统的协调发展逐渐增强，但耦合协调水平仍然处于较低阶段，2018—2022年两系统耦合协调水平处于快速增长阶段，由初级协调转变为中级协调；3）农村产业融合指数对农村生态环境指数的脉冲响应值始终为正值，对生态环境的动态冲击响应效果为递增的促进作用，其中农业产业链延伸对生态环境的动态冲击响应效果整体上表现为先增后降的促进作用，农业多功能拓展和农业服务业融合对生态环境的动态冲击响应效果呈现出递增的促进作用，产业融合能有效地促进农村生态环境改善；生态环境对农业服务业的动态冲击响应为正向的促进作用，对农业产业链延伸指数、农业多功能拓展指数的脉冲响应始终为负，表明生态环境对农业产业链延伸和农业多功能拓展的动态冲击响应表现为递增的抑制作用；4）方差分解显示农业产业链延伸、农业服务业融合和农业多功能拓展的变动对农村生态环境质量的平均解释贡献率分别为18.08%、24.09% 和0.17%，生态环境质量自身的平均贡献度为57.66%。
