农业服务化对粮食产业高质量发展的影响效应及作用机制

The Effect and Its Mechanism of Agricultural Servitization on High-quality Development of Grain Industry

农业服务化是推动粮食产业转型升级、实现高质量发展的新战略引擎。利用中介效应、地理加权回归和门槛面板模型从供求两方面论证农业服务化对粮食产业高质量发展的影响效应及作用机制。研究发现:农业服务化通过分工深化和市场竞争两种中介渠道对粮食产业高质量发展产生U型影响,且这种影响存在空间分异性;分工深化的规模经济效应有利于提升农业服务化的粮食产业质量升级效应,但竞争不足的资源错配效应对其存在遮蔽作用;城镇化率、农民人均收入和土地经营规模均能异质性地调节农业服务化对粮食产业的质量升级效应,间接导致了其空间分异性。为实现粮食产业高质量发展,应在追求规模经济的同时,建立有效竞争机制,加速农村劳动力转移,缩小区域间收入差距,推进适度规模化经营,以最大限度地释放农业服务化红利。

Agricultural servitization has become a new strategic engine to promote the transformation and upgrading of grain industry and achieve high-quality development. Using the intermediary effect model,geographically weighted regression and threshold panel model,this paper demonstrates the effect and mechanism of agricultural servitization on the high-quality development of grain industry from two aspects of supply and demand. It is found that through deepening division of labor and market competition intermediary channels,agricultural servitization has a U-shaped effect on the high-quality development of grain industry,which has spatial differentiation;the scale economy effect of deepening division of labor has a strengthening impact of agricultural servitization on quality upgrading of grain industry,while the resource mismatch effect of insufficient competition has a shadowing effect;urbanization rate,farmers’ income and land scale can heterogeneously regulate the impact of agricultural servitization on quality upgrading of grain industry,which indirectly leads to the spatial differentiation. In order to realize the high-quality development of grain industry,it is necessary to establish an effective competition mechanism in the pursuit of scale economy,accelerate the transfer of rural labor force,narrow the income gap between regions,and promote moderate scale operation,so as to release the "agricultural servitization dividend"to the maximum extent.
