利用长江经济带110个地市1990~2013年R&D投入与经济增长水平的相关面板数据,通过单位根检验、协整性检验和面板数据模型,对R&D经费投入和人员投入与区域经济增长的影响进行了分析。结果表明:1长江经济带各市的经济增长与R&D投入存在长期稳定的关系,R&D短期投入对区域经济增长的影响则存在着一定的滞后效应;2R&D人员投入产出弹性高于R&D经费投入,说明区域经济增长对R&D人员的依赖性更大;3R&D投入表现出东部地区高于中部地区,中部地区高于西部地区,但R&D投入对区域经济增长的影响则表现出中西部大于东部的现象,造成这一现象的原因在于所处发展阶段的不同和东中西区域经济特征不同。最后,从加大R&D经费投入强度、制定R&D投入中长期计划等方面提出了促进区域经济增长的建议。
Using the panel data of R & D investment and economic growth in 110 cities in the Yangtze River economic belt from 1990 to 2013, the influence of R & D investment, personnel input and regional economic growth through unit root test, cointegration test and panel data model Analyzed. The results show that: (1) There is a long-term and stable relationship between the economic growth and R & D investment in cities along the Yangtze River economic belt; the short-term input of R & D has some lag effect on the regional economic growth; the input-output elasticity of 2R & D personnel is higher than that of R & D investment 3R & D investment shows that the investment in 3R & D is higher in the eastern region than in the central region and higher in the central region than in the western region. However, the impact of R & D investment on regional economic growth shows that the central and western regions are greater than the eastern region, resulting in The reason for this phenomenon lies in the different stages of development and the different economic characteristics of the eastern, central and western regions. Finally, we put forward suggestions to promote regional economic growth from the aspects of increasing the intensity of R & D spending and formulating medium and long-term plans for R & D investment.
