摘要
[目的/意义]通过深入分析创新投入对经济增长的门槛效应,为优化创新资源投入,促进区域经济健康协调发展提供有益参考。[方法/过程]基于2004-2014年30个省份的面板数据,分别利用Theil熵与Moran I指数验证了中国区域经济发展存在明显的差异性与空间集聚特征;构建Hansen非动态面板门槛回归模型实证分析创新投入对区域经济增长的影响。[结果/结论]研究发现创新投入对区域经济增长存在双重门槛效应,当基础设施建设水平低于低门槛值时,创新投入对区域经济增长的促进作用最强;在高低门槛之间,创新投入对区域经济增长的促进作用减弱,人员方式的创新投入的影响不再显著;高于高门槛值时,创新投入的影响效应进一步减弱,人员方式的创新投入对区域经济增长的影响仍然不显著;研发经费投入的影响效应强于研发人员投入。由此认为区域经济增长需要创新投入,但必须充分考虑各地区基础设施建设的门槛效应。
[ Purpose/Significance ] Through in-depth analysis of the threshold effect of the innovation input on economic growth effect, we can provide some beneficial references for optimizing the innovation resources input, and promote the coordinated and healthy develop- ment of regional economy. [ Method/Process] Based on the panel data of 30 provinces from 2004 to 2014, the study respectively uses Theil entropy and Moran I index to verify the obvious differences and spatial agglomeration of regional economic development in China, and builds Hansen threshold regression model to analyze the effect of innovation input on regional economic growth. [ Result/Conclusion] Results show that the innovation input has significantly dual threshold effect on regional economic growth. When the level of infrastructure construction is beneath the lower-threshold value, the promoting effect of innovation input on regional economic growth is the strongest ; when the level of infrastructure construction is between high and low thresholds value, the promoting effect of innovation input on regional economic growth becomes weaker, and the impact of staff input is no longer significant; when the level of infrastructure construction is beyond high threshold value, the effect of innovation input is the weakest and the impact of staff input is still not significant. Furthermore, compared with staff input, the effect of R＆D expenditure is stronger. Thus, the results indicate that the regional economic growth requires innovation input, but it must fully consider the threshold effect of the regional infrastructure construction.
