Research On The Effect Of Foreign Direct Investment And Industrial Agglomeration On The Efficiency Of Green Innovation

The deepening openness to the outside world is driving China’s economic transformation towards high-quality development,while the crude development model is seriously affecting the sustainable development of the economy and society,so it is urgent to take the path of "innovation" and "green" development.Foreign direct investment can promote green innovation by increasing capital accumulation,strengthening technology spillover,introducing advanced management experience,and enhancing market competition,etc.The scale of foreign investment in China is expanding year by year,but there are still real problems such as slowing down of foreign investment growth,unbalanced total investment,regional imbalance of investment and widening of regional development differences,and uneven investment in industries inhibiting industrial transformation and upgrading.In the process of deepening reform and opening up,FDI inflow and local industrial agglomeration have emerged new features such as geospatial coupling and mutual promotion,and the relationship between them and innovation is close,so it is necessary to study their influence on green innovation in China.Land price has a very important impact on enterprise production and operation,government financial assets,etc.It affects regional housing prices and the inflow of innovative talents on the one hand,and influences FDI location selection,urban industrial structure upgrading and enterprise innovation on the other.In recent years,the "two-handed" land supply strategy of the local government of offering industrial land at low prices for the purpose of attracting investment and improving economic development and commercial land at high prices for the purpose of increasing local fiscal revenue has led to a "scissor difference" in land prices in China’s land market.As an important policy tool of the government,it is important to pay attention to the impact of commercial land prices and industrial land prices,which are two different price formation mechanisms,on the efficiency of green innovation.As an important policy tool of the government,it is beneficial to find the right starting point to improve the business environment,optimize the industrial structure,and enhance the innovation vitality of cities.Therefore,it is important to study the role of industrial agglomeration and different types of land prices in the relationship between FDI and regional green innovation efficiency,to improve regional green innovation efficiency in terms of optimizing the types of investment attraction scale and industrial agglomeration level,and to improve the land price mechanism,in order to promote regional socio-economic environmental coordination.This paper constructs the green innovation efficiency evaluation index system based on the input-output perspective,uses the panel data of 108 prefecture-level cities along the Yangtze River economic belt from 2007-2019 to reveal the spatial and temporal changes of green innovation efficiency at the scale of local cities,and explores the intermediary path of industrial agglomeration,the regulation path of commercial land price and industrial land price under the influence of FDI on green innovation The paper draws the following conclusions.This paper draws the following conclusions:(1)the green innovation efficiency value of the Yangtze River Economic Zone from 2007 to 2019 shows an overall upward trend,but there is spatial unevenness,with the highest overall efficiency in the downstream,the second highest in the upstream,and the lowest in the midstream,showing a distribution pattern of "strong in the east and weak in the west";(2)FDI and green innovation efficiency and industrial agglomeration all show a "first up,then down" pattern.FDI and green innovation efficiency and industrial agglomeration have an inverted U-shaped non-linear relationship of "first up then down",with obvious inflection point effect,and significant intermediary effect of industrial agglomeration,with an intermediary strength of 3.84%.There is regional heterogeneity in this conclusion,the intermediation effect of upstream and downstream regions holds and the intensity is6.4% and 6.6% respectively,while the intermediation effect of midstream regions does not hold.(3)The price of industrial land not only inhibits the non-linear effect of FDI on green innovation efficiency,but also inhibits the driving effect of industrial agglomeration on green innovation efficiency.By region,the moderating effect of industrial land prices on both direct and indirect paths is not significant in upstream regions,significant in midstream regions,and significant in downstream regions.The price of commercial land not only promotes the positive effect of industrial agglomeration,but also enhances the effect of FDI scale on green innovation efficiency after crossing the threshold,making the inverted U-shaped curve steeper.Based on the above study,the policy insights obtained from this paper are:(1)to accurately grasp and scientifically assess the impact of FDI on regional green innovation efficiency,explore the turning point of green innovation efficiency,adjust the scale and type of foreign investment introduced,and actively avoid the negative effects of foreign investment.(2)Improve the infrastructure construction of the agglomeration area,pay attention to the matching degree of foreign investment and local enterprises,strengthen the training and introduction of innovative talents,actively cultivate new industrial clusters,and play the driving role of agglomeration economy.(3)Regulate land prices according to local conditions,reduce the dependence on land finance,optimize the land market-oriented operation mechanism,use the hierarchical differences in land prices to optimize the structure and quality of foreign investment,improve the level of industrial agglomeration,and thus enhance the level of green innovation in the city.
