在对互联网技术和区域创新效率研究的基础上，基于电子商务商业模式视角，系统分析了电子商务发展、私营制造业集聚，以及二者的交互作用对区域创新效率的影响，并利用2014－2017年我国30个省份的面板数据，运用OLS回归分析开展实证研究。结果表明，电子商务发展对区域创新效率产生先升后降的倒“U”型影响，而私营制造业集聚在其中发挥了显著的调节作用。在政策建议方面，提升区域创新效率水平，应根据各省电子商务发展实际情况，推动区域电子商务发展；加强市场环境建设和网络知识产权保护力度，保障电子商务持续健康发展；构建良好的区域创新支持体系，促进私营制造业转型升级。

Based on the research of Internet technology and regional innovation efficiency, this paper systematically analyzes the impact of e-commerce development, private manufacturing agglomeration, and their interaction on regional innovation efficiency from the perspective of e-commerce business model. Using panel data of 30 provinces in China from 2014 to 2017 and OLS regression analysis, the empirical research results show that the development of e-commerce has an inverted "U" effect on the regional innovation efficiency, while private manufacturing industry agglomeration plays a significant regulatory role. Policy recommendations are that, to improve regional innovation efficiency, governments need to promote the development of regional e-commerce according to the actual situation of e-commerce development in each province; strengthen the construction of market environment and the protection of network intellectual property rights to ensure the sustainable and healthy development of e-commerce; build a good innovation support system to promote the transformation and upgrading of private manufacturing industries.
