本文运用空间动态系统广义矩的估计技术,基于1998至2008年中国大陆30个省级面板数据,考察了金融发展、金融市场化和知识产权保护对技术创新效率的影响。研究发现,金融发展和知识产权保护积极推动了技术创新效率的改进,而金融市场化则妨碍了技术创新效率的提升。此外,知识产权保护强化了金融发展对技术创新效率改进的积极作用,而弱了金融市场化对技术创新效率改进的消极作用,但作用程度并不大。进一步研究发现,中国技术创新效率除了具有较强的路径依赖性外,而且其空间效应强度会随着区域因素的不同而发生明显变化,其中经济因素是技术创新效率空间聚集的主因。本文为理解市场化改革背景下中国技术创新效率的影响因素提供了一个新的视角,也为理解金融发展、金融市场化和知识产权保护对于内生经济增长的影响机制提供了新的经验证据。
Abstract
Using dynamic spatial panel data analysis techniques, this paper investigates the effects of financial development, financial marketization and intellectual property protection on the technological innovation efficiency based on the panel data from 30 provincial areas from 1998 to 2008 in Mainland China. The results show that, financial development and intellectual property protection have a positive effect on the technological innovation efficiency of China, but financial marketization has a negative effect on it. In addition, intellectual property protection has strengthened the positive effect of financial development on the technological innovation efficiency of China, but it has lessened the negative effect of financial marketization on the technological innovation efficiency of China. Through further studies, it was detected that the technological innovation efficiency of China is obvious path dependent, and with the difference of regional factor, its space effect intensity changes. However, the main reason about spatial aggregation of technological innovation efficiency in China is economic factors. This paper provides a new perspective to understand the influencing factors of China's technological innovation efficiency under the background of market-orient reform, and it also provides new evidence to understand the influencing mechanism of financial development, financial marketization and intellectual property protection on endogenous economic growth.
