粮食主产区农业社会化服务对农业碳排放强度的影响及空间溢出效应

The impact of agricultural socialization service on agricultural carbon emission intensity in major grain-producing areas and its spatial spillover effect

  • 摘要: 粮食主产区承担着粮食和生态的双安全重担, 探究其农业社会化服务对农业碳排放强度的影响机制, 对于推进粮食主产区农业低碳转型具有现实意义。本文通过选取粮食主产区13个省份(自治区)近15年面板数据, 运用普通最小二乘法、中介效应模型和时间固定效应的空间杜宾模型, 进一步探讨农业社会化服务对农业碳排放强度的直接影响、间接影响和空间溢出效应。本文主要结论如下: 1)农业社会化服务对农业碳排放强度具有显著“减碳效应”, 从农业社会化服务的4个维度来看, 农业信息化服务、农村公共服务和农业金融保险均显著降低了农业碳排放强度, 而农资服务提高了农业碳排放强度。2)基于经济发展水平将粮食主产区划分为三大流域发现: 长江流域和黄河流域农业社会化服务一定程度上降低了农业碳排放强度, 而松花江流域农业社会化服务在一定程度上提高了农业碳排放强度。3)农业经营规模和农业财政扶持在农业社会化服务对农业碳排放强度的作用过程中存在中介效应, 即农业社会化服务能够通过促进农业经营规模扩大和降低农业财政扶持所带来的负面环境效应间接降低农业碳排放强度。4)粮食主产区农业社会化服务对农业碳排放强度具有较强的负向空间溢出效应, 本省份农业社会化服务每增加1%, 降低邻近省份农业碳排放强度7.04%。基于上述结论得出如下政策启示, 政府应提高粮食主产区各省份农业社会化服务发展水平, 合理规划农业社会化服务发展方向和范围, 并构建粮食主产区各省份农业社会化服务和农业碳减排交流渠道, 以此来降低粮食主产区农业碳排放强度, 助力粮食主产区早日实现农业绿色低碳化转型。

     

    Abstract: The major grain producing areas bear the double security burden of food and ecology, and it is of practical significance to explore the influence mechanism of socialized service for agriculture on the intensity of agricultural carbon emissions in order to promote the low-carbon transformation of agriculture in the major grain producing areas. This paper selects panel data from 13 provinces (autonomous regions) in major grain producing areas in recent 15 years, and uses the ordinary least square method, the intermediary effect model and the Spatial Durbin model of time fixed effect to further explore the direct and indirect impacts of agricultural socialization services on agricultural carbon emission intensity, and the spatial spillover effects. The main conclusions of this paper are as follows: 1) Socialized service for agriculture has a significant “carbon reduction effect” on agricultural carbon emission intensity. From the perspective of four dimensions of socialized service for agriculture, agricultural information service, rural public service and agricultural finance and insurance all reduce agricultural carbon emission intensity, while agricultural material service increases agricultural carbon emission intensity. 2) Based on the level of economic development, the main grain -producing areas were divided into three major river basins. It was found that the agricultural socialization service in the Yangtze River basin and the Yellow River basin reduced the agricultural carbon emission intensity to a certain extent, while the socialized service for agriculture in the Songhua River basin increased the agricultural carbon emission intensity to a certain extent. 3) Agricultural operation scale and agricultural financial support have mediating effects on agricultural carbon emission intensity, that is, socialized service for agriculture can indirectly reduce agricultural carbon emission intensity by promoting the expansion of agricultural operation scale and reducing the negative environmental effects caused by agricultural financial support 4) Socialized service for agriculture in the main grain-producing areas have a strong negative spatial spillover effect on the intensity of agricultural carbon emissions, and every 1% increase in socialized service for agriculture in this province reduces the intensity of agricultural carbon emissions in neighboring provinces by 7.04%. Based on the above conclusions, the government should improve the development level of socialized service for agriculture in the provinces of the main grain-producing areas, reasonably plan the development direction and scope of socialized service for agriculture, and build communication channels between socialized service for agriculture and agricultural carbon emission reduction in the provinces of the main grain producing areas, so as to reduce the intensity of agricultural carbon emissions in the main grain producing areas, and to assist in the transformation of the main grain producing areas into a green and low-carbon agriculture at an early date.
