价值链视角下金融深度、金融宽度与区域创新效率——基于DEA-Tobit两阶段模型
Finance depth、Finance width and Regional Innovation Efficiency in the view of Innovation Value Chain: Based on the DEA-Tobit Model
【摘要】 根据创新价值链理论,将技术创新划分为科技研发、成果转化两个相互关联的子过程。利用2005—2015年中国30个省份的面板数据,使用DEA模型,测算各地区在两个阶段的创新效率。在此基础上,使用面板Tobit回归,实证检验了金融发展的两种模式,即金融宽化、金融深化与不同阶段技术创新效率的关系。研究发现,金融深度和金融宽度都能够提高技术创新效率,但在科技研发阶段,金融深度对区域创新效率的影响更加显著,在成果转化阶段,金融宽度的作用更加明显。
【Abstract】 Taking the perspective of innovation value chain,we divided the technology innovation into two interrelated processes,the R&D process and the industrialization process. Then we measured the regional innovation efficiency of each process using 2005-2015 panel data of 30 provinces in China by DEA method. Furthermore,we tested the relationship of financial development and regional innovation efficiency by panel Tobit model. The study found that: the financial depth and financial width can both improve the innovation efficiency. In the R&D process,the financial depth has a more significant effect on the regional innovation efficiency. In the industrialization process,the financial width can improve the innovation efficiency much more compared with financial depth.
