摘要/Abstract

摘要： 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。

Abstract: The Chinese government put forward the development strategy of the Yangtze River Economic Zone in September 2014. The proportion of GDP of the Yangtze River Economic Zone in China is 45.62%, and many scholars expected the proportion would up to 50% in 2020. The relationship between R&D input and economic growth has been the hot study in the economics, economic geography and so on, and research has found that R&D input was an important effect on regional economic growth and the impact of R&D input on economic growth was positive correlation, but some deficiencies were still existed. Based on the C-D model, we built the relationship model between R&D input and economic growth through the panel data of R&D input and economic growth of 110 cities during 1990-2013 in Yangtze River Economic Zone. With the help of Eviews7.2, we finessed the unit root test, co-integration test and built the panel data model, which can be used to analysis the impact of R&D input on regional economic growth. The results showed that: (1) The relationship between R&D input and regional economic growth was long-term and stable, and there was a certain hysteresis effect between R&D short-term input and regional economic growth, the elasticity of R&D input in the short-term was higher than the long-term.; (2) The relationship between R&D input and regional economic growth was positive correlation significantly, but the elasticity coefficient of R&D personnel input (the average of Yangtze River Economic Zone was 2.351) was higher than R&D expenditure input (the average of Yangtze river economic belt is 1.013), which showed that regional economic growth dependences much more on R&D personnel. In the other words, talent (person with ability) was more important than money to regional economic growth; (3) The spatial differences of R&D input in the Yangtze River Economic Zone was significant, and R&D input in the area of the lower of Yangtze River was the highest, but the impact of R&D input on regional economic growth in the area of the lower Yangtze River was the lowest. Why was the impact of R&D input on regional economic growth different among the regions? The growth of regions would result from the balance between their stocks of both local and global (i.e. non-local) network capital, but the R&D input of this article was local, and the regions in the area of the lower of Yangtze River were export-oriented economy, so the impact of R&D input on regional economic growth in the area of the lower of Yangtze River was less significant than the middle and the upper of Yangtze River. At last, in order to promote regional economic growth, this article put forward the proposal of increasing the intensity of R&D input, making the medium and long-term planning for R&D input, and improving the achievements conversion rate of scientific and technological. In the future, we can incorporate the network capital of innovation network of local and global into the regional economic growth model, which can help us to better research the relationship between regional economic growth and innovation.

Key words: R&D input, economic growth, fixed-effects variable-coefficient model, the Yangtze River Economic Zone
