摘　　要：以2012—2021年中国省际面板数据为样本,构建中介效应模型和空间杜宾模型探究知识产权保护对农产品出口竞争力的影响,讨论要素价格扭曲在其中起到的中介效应,测算知识产权保护对农产品出口竞争力的直接效应和空间溢出效应,并以东、中、西部地区为标准进行了异质性分析。主要得出以下结论:第一,知识产权保护、资本价格扭曲、城镇化水平、环境规制、交通设备水平和数字经济的发展能够显著提升农产品出口竞争力,但劳动力价格扭曲和产业集聚程度过高会抑制农产品出口竞争力发展。第二,知识产权保护的直接促进作用和其缓解劳动力价格扭曲所产生的正向中介作用,大于知识产权保护缓解资本价格扭曲从而减少“成本优势”来降低农产品出口竞争力的负向中介作用。第三,中国农产品出口竞争力具有显著的空间相关性,知识产权保护具有显著的正向空间溢出效应和直接效应,且存在显著的区域异质性。从溢出效应看,东部地区>中部地区>西部地区;从直接效应看,中部地区>东部地区>西部地区。Based on the inter-provincial panel data of China from 2012 to 2021,this paper constructs the mediating effect model and the spatial Durbin model to explore the impact of intellectual property protection on the export competitiveness of agricultural products,discusses the mediating effect of factor price distortion,and calculates the direct effect and spatial spillover effect of intellectual property protection on the export competitiveness of agricultural products,and conducts heterogeneity analysis taking the eastern,central,and western regions as standards.The main conclusions are as follows:Firstly,the protection of intellectual property rights,capital price distortion,urbanization level,environmental regulation,transportation equipment level and the development of digital economy can significantly improve the export competitiveness of agricultural products.However,the distortion of labor price and excessive industrial agglomeration will inhibit the development of export competitiveness of agricultural products.Secondly,the direct promoting effect of intellectual property protection and the positive mediating effect of alleviating labor price distortion are greater than the negative mediating effect of intellectual property protection in alleviating capital price distortion and thereby reducing“cost advantage”to lower the export competitiveness of agricultural products.Thirdly,the export competitiveness of China’s agricultural products has significant spatial correlation,and the protection of intellectual property rights has significant positive spatial spillover effect and direct effect,with significant regional heterogeneity.From the perspective of spillover effect,the eastern region>the central region>the western region;From the perspective of direct effect perspective,the central region>the eastern region>the western region.
