摘要
自主研发、引进技术、购买国内技术、更新改造几种创新路径对高技术产业具有十分重要的意义.由于不同计量模型各有优缺点,各模型的研究结论并不相同,而针对同一问题、同一数据根本就没有最佳模型,所以本文首先采用面板混合回归、面板数据模型、动态面板模型、面板联立方程模型、空间面板模型同时进行研究,然后采用元分析对5种研究结果加以整合,得到唯一结论.研究表明,自主研发绩效显著;更新改造是创新的必要补充,绩效良好;引进技术和购买国内技术总体绩效不高;元分析有利于提高研究的稳健性.
Abstract
Innovation paths, which including independent R&D, technological introduction, purchasing domestic technology and technical renovation and transformation, are of great significance on high-tech industry.Each econometric model has advantages and disadvantages,and the conclusions of models are not the same.There is no optimization model, so in this paper, firstly we use panel mixed regression, panel data model, dynamic panel model, panel simultaneous equation model and spatial panel model to do research respectively, then using a meta-analysis to integrate the five kinds of research results, finally arrive at an only conclusion.The results show that the performance of independent R&D is significant, technical renovation and transformation is the necessary supplement of innovation, whose performance is good.The global performance of technological introduction and purchasing domestic technology is not good.Meta-analysis is beneficial to improve the robustness of our research.
