| Over the past 40 years of Reform and Opening Up,China's economy has achieved sustained and rapid growth.China's GDP rose from 367.9 billion Yuan to 91.93 trillion Yuan in 2018,with an average annual growth rate of 9.5%,far higher than the world economy's average annual growth rate.However,for a long time,China's economic growth has shown the characteristics of extensive growth mode,which also led to a series of environmental problems such as increased pollution and haze,making the economic growth unsustainable.Especially since 2010,the Chinese economy has entered a “New Normal”.There has been considerable downward pressure on China's economic growth.The problems of “Disenchantment” and overcapacity are intertwined,which makes China's economic growth face many uncertainties.How to cultivate new driving forces and transform the economic growth mode,so as to solve the growth dilemma,has become an urgent problem.In this case,the Chinese government takes innovation driven development as an important starting point to break through the bottleneck of growth,encouraging mass entrepreneurship and innovation,and increasing support for scientific and technological innovation.However,the innovation system reform has gradually entered the “deepwater area”,and the deep-seated and structural contradictions have become increasingly apparent.Scientific and technological innovation has fallen into a prominent dilemma in the process of improving Total factor productivity(TFP).To achieve innovation-driven development,we still face adjustments in innovation input and innovation policy structure.This is highlighted by the structural divergence between innovation input and TFP.From 2004 to 2017,China's investment in science and technology innovation increased at an average annual rate of over 18.5%,and the total investment in research and development from local governments increased at an average annual rate of over 11.3%.This leads to the thinking of this paper: in the window period of transforming the economic growth mode and solving the growth dilemma,can the continuous increase of R&D elements promote the transformation of economic growth mode? In this process,what role will the innovation pursuit strategy and accelerating the pace of innovation pursuit play?Based on the endogenous growth theory,this paper puts the government's innovation pursuit behavior into the intermediate production link of innovation production activities,constructs an endogenous growth model of intermediate products which includes different types of R&D activities and government's innovation pursuit behavior.This paper deduces the possible relationship among catch-up strategy of innovation,allocation of R&D factors and transformation of economic growth mode through mathematical model.On this basis,this paper manually collects the annual government work reports of each provincial administrative unit in China and the provincial panel data of China from 2004 to 2017,uses the word frequency analysis technology based on Python to extract the government's attention to innovation as a agent variable for the implementation of innovation catch-up strategy.Then the spatial measurement model is used to test the impact of independent innovation and imitation innovation,basic research and applied research on the transformation of economic growth mode.Furthermore,the roles of direct government R&D spending and indirect innovation encouraging signal are investigated.Finally,the appropriate innovation catch-up strategies that local governments can adopt under their own innovation path and innovation stage are formed.The main conclusions of this paper include the following aspects.(1)Compared with eastern and central China,the level of economic intensification in Western China has been at the lowest level.On the whole,the level of economic intensification in the whole country shows a downward trend year by year.However,the areas with higher level of economic intensification are fewer and fewer,and the “leader region” of high-quality growth is missing.(2)Compared with eastern and central China,the R&D input in Western China has been relatively little.During the research period,the growth rate of the four types of R&D elements investment shows a step-by-step downward trend in the whole country.The growth rate of basic research is significantly higher than that of the other three types of innovation investment,even in the trend of negative growth for many years.It also shows that with the innovation-driven development strategy put forward,China is more and more aware that promoting high-quality innovation requires strong basic research capabilities.(3)On the whole,the focus on innovation is the strongest in the East,the second in the middle and the weakest in the West.After 2014,the innovation-driven development strategy has been put in a very prominent position.At this time,local governments at all levels have paid more attention to innovation,especially in the government work report.However,there are still some local governments that have not paid enough attention to innovation.There is an obvious gap among regions in the importance of innovation.This gap has a further trend of expansion.(4)As the four channels of R&D input,independent innovation,imitative innovation,basic research and application research have an inverted U-shaped impact on regional economic intensification.After the robustness test and endogeneity consideration,the conclusion is still credible.(5)After considering the catch-up strategy of innovation catch-up strategy implemented by the government,it is found that the government's direct R&D spending and indirect innovation encouraging signal show heterogeneity in the process of four innovation modes affecting the transformation of economic growth mode.The former is mainly reflected in the “extension effect” of weakening the inverted U-shaped relationship,while the latter is reflected in the “compression effect” of strengthening the inverted U-shaped relationship.(6)Based on the running track of the inverted U-shaped curve,the “extension effect” and “compression effect” of government innovation support,this paper puts forward the appropriate catch-up strategy of innovation,namely “forward compression and backward extension”.After calculating the effective range of government's direct R&D spending and indirect innovation encouraging signal intensity by using the spatial smooth transformation model,combining the critical values of the input scale of four innovation modes,this paper constructs an appropriate way matrix of catch-up strategy of innovation according to the current situation of innovation in each region.This paper expands the research perspective of the transformation of economic growth mode.The conclusions are not only the review and reflection of innovation catch-up strategy,but also an exploration of effective ways of economic growth mode transformation.At the same time,the conclusions also provide a decision reference for the rational regulation of investment in scientific and technological innovation,and the avoidance of "R&D worship". |
