基于SFA模型的辽宁省装备制造业技术创新效率及影响因素研究

装备制造业很大程度上影响着国民经济发展，掌握其技术创新效率有助于行业和地区的创新发展。基于辽宁省装备制造业最新数据，运用随机前沿法构建技术创新效率测算和影响因素模型并通过假设检验。研究表明：辽宁省装备制造业总体技术创新效率情况稳中趋好，其中7个行业间效率差距较小，且变化幅度相对稳定；同时研发人员专业化程度、企业所有权结构、对外开放度对辽宁省装备制造业技术创新效率起主要促进作用。

Research on Technology Innovation Efficiency and Influencing Factors of Equipment Manufacturing Industry in Liaoning Province Based on SFA Model

The equipment manufacturing industry greatly affects the development of the national economy, and its technological innovation efficiency is conducive to the innovative development of the industry and the region. Based on the latest data of Liaoning equipment manufacturing industry, the stochastic frontier approach is used to construct a model of technological innovation efficiency measurement and influencing factors and passed the hypothesis test. The research shows that the overall technological innovation efficiency of Liaoning Equipment Manufacturing Industry is stable and improving, of which the efficiency gap between 7 industries is small, and the range of changes is relatively stable, while the degree of specialization of R&D personnel, the ownership structure of enterprises, and the degree of opening up play a major role in promoting the technological innovation efficiency of Liaoning equipment manufacturing industry.
