农产品电商集群企业多维邻近性对协同创新绩效的影响

利用湖北、江西和浙江3省312家农产品电商集群企业的调查数据，对多维邻近性与协同创新绩效的关系进行了研究，并探讨了多维邻近性之间的交互作用对协同创新绩效的影响。结果表明:1)农产品电商集群企业社会邻近性与技术邻近性均正向影响协同创新绩效；地理邻近性与协同创新绩效之间存在倒“U”型关系，高度的地理邻近性会带来区域竞争、产品竞争和知识外溢，降低企业协同创新绩效。2)农产品电商集群企业地理邻近性与技术邻近性的交互项对协同创新绩效发挥正向作用，呈现互补机制；社会邻近性与技术邻近性的交互项对协同创新绩效产生负向影响，呈现替代机制；地理邻近性与社会邻近性的交互项对协同创新绩效影响不显著。因此，农产品电商集群企业要注重与合作企业良性协同创新关系的建立，降低区域内同质性农产品的区域竞争和产品竞争，同时政府和相关组织要加强对农产品电商企业的技术技能培训，发挥数字技术对农产品电商企业创新发展的推动作用。

Impact of multidimensional proximity of clustered agricultural e-commerce firms on synergetic innovation performance

Based on the survey data of 312 clustered agricultural e-commerce firms in Hubei, Jiangxi and Zhejiang provinces, the relationship between multidimensional proximity and synergetic innovation performance is explored, and the impact of the interaction effect between multidimensional proximity on synergetic innovation performance is investigated. The results show that: 1)Both the social proximity and technological proximity of clustered agricultural e-commerce firms positively affect synergetic innovation performance. There is an inverted U-shaped relationship between geographic proximity and synergetic innovation performance, and a high degree of geographic proximity would bring regional competition, product competition and knowledge spillover, and reduce the synergetic innovation performance. 2)The interaction items of geographic proximity and technological proximity of clustered agricultural e-commerce firms play a positive role in the synergetic innovation performance, presenting a complementary mechanism. The interaction items of social proximity and technological proximity have a negative impact on the synergetic innovation performance, presenting an alternative mechanism. The interaction items of geographic proximity and social proximity have no significant impact on synergetic innovation performance. Therefore, firms should pay attention to the establishment of a benign synergetic innovation relationship with cooperative firms to reduce regional competition and product competition for homogeneous agricultural products in the region. At the same time, the government and relevant organizations should strengthen the technical skills training for agricultural e-commerce firms, and give full play to the role of digital technology in promoting the innovation and development of agricultural e-commerce firms.
