购买国外专利技术与自主研发是企业获取技术的两种重要的互补性途径。由于两者都需要大量的资金支持,企业的融资状况变化会对他们产生怎样的影响值得关注。本文使用2012年世界银行中国投资环境调查报告中的制造业企业数据,采用多项式选择模型检验融资约束条件下企业购买国外专利技术与自主研发之间的协同效应,以及两者对融资约束的非对称性反应。研究发现企业的融资能力是影响企业技术获取的重要因素。融资约束得到缓解时,两者之间会产生极强的协同效应,且自主研发对融资条件变化的反应更大、更显著。因此,企业在注重购买专利技术与自主研发协调发展的同时,应以自主研发作为未来技术获取的主要途径。
Buying foreign patented technology and independent research and development are two important complementary ways for enterprises to acquire technology. Because both require significant financial support, it is worth noting what impact these changes in the financing landscape will have on them. In this paper, we use the data of manufacturing enterprises in the World Bank China Investment Environment Survey 2012 to test the synergies between the foreign-funded technologies and the independent R & D of enterprises under the financing constraint by using the polynomial selection model, and the asymmetry of the financing constraints between the two Sexual response. The study found that the financing ability of enterprises is an important factor affecting the technology acquisition of enterprises. When financing constraints are mitigated, there will be a strong synergistic effect between the two, and the independent research and development will respond more and more significantly to changes in financing conditions. Therefore, enterprises pay attention to the coordinated development of purchasing patented technology and independent research and development, and should take independent research and development as the main way to acquire future technologies.
