农产品电商集群企业地理集中度、双重知识网络嵌入与协同创新绩效

协同创新是农产品电商集群企业高质量发展的重要内容，对实现小农户生产与大市场消费有效衔接和农业现代化发展具有重要意义。本文利用湖北、江西和浙江3省358家农产品电商集群企业的微观调研数据，运用多层次回归分析和Bootstrap分析方法，分析农产品电商集群企业地理集中度、双重知识网络嵌入与协同创新绩效间的关系，探究资产专用性和环境不确定性的调节作用。结果表明，农产品电商集群企业地理集中度和协同创新绩效处于较高水平，双重知识网络嵌入、资产专用性和环境不确定性均处于中等水平。地理集中度、双重知识网络嵌入、资产专用性与协同创新绩效显著正相关，环境不确定性与协同创新绩效显著负相关。农产品电商集群企业地理集中度正向影响协同创新绩效。农产品电商集群企业双重知识网络嵌入在地理集中度与协同创新绩效间发挥部分中介作用。资产专用性正向调节双重知识网络嵌入与协同创新绩效的正向关系；环境不确定性负向调节双重知识网络嵌入与协同创新绩效的正向关系；资产专用性和环境不确定性对双重知识网络嵌入与协同创新绩效的正向关系存在联合调节效应。因此，农产品电商集群企业要加强与集群内外部企业合作创新，注重数字技术设备的投入和更新，构...

Geographical concentration, dual knowledge network embedding, and collaborative innovation performance of clustered agricultural e-commerce firms

Collaborative innovation is an important part of the high-quality development of clustered agricultural e-commerce firms. It is of great significance to realize the effective connection between small-scale production and large-scale consumption and the development of agricultural modernization. Based on a micro survey data of 358 clustered agricultural e-commerce firms in Hubei, Jiangxi and Zhejiang provinces, this paper adopts the multi-level regression analysis and the bootstrap analysis methods to analyze the relationship among geographical concentration, dual knowledge network embedding, and collaborative innovation performance of clustered agricultural e-commerce firms and to explore the moderating effect of asset specificity and environmental uncertainty. Results show that the geographical concentration and collaborative innovation performance of clustered agricultural e-commerce firms are at a high level, while dual knowledge network embedding, asset specificity, and environmental uncertainty are at a medium level. Geographical concentration, dual knowledge network embedding, and asset specificity are positively correlated with collaborative innovation performance, while environmental uncertainty is negatively correlated with it. Geographical concentration of clustered agricultural e-commerce firms positively affects collaborative innovation performance. Dual knowledge network embedding plays a partial mediating role between geographical concentration and collaborative innovation performance. Asset specificity positively moderates the positive relationship between dual knowledge network embedding and collaborative innovation performance, while environmental uncertainty plays a negative moderating role. Meanwhile, asset specificity and environmental uncertainty jointly moderate the positive relationship between dual knowledge network embedding and collaborative innovation performance. Therefore, clustered agricultural e-commerce firms should strengthen cooperative innovation with internal and external firms of cluster, pay attention to the input and renewal of digital technology equipment, build competitive advantages based on knowledge resources, grasp development opportunities in an uncertain environment, and realize high-quality collaborative innovation development.
