| In order to realize the transformation from "made in China" to "created in China",the State Council issued "made in China 2025" in 2015,and put forward the first ten-year action plan for the implementation of the strategy of building a strong manufacturing country,which promoted the manufacturing industry to improve quality and efficiency and achieved remarkable results.The improvement of R&D innovation quality still faces many restrictions,among which the segmentation of regional market has been criticized by all sectors of society.However,there is no clear answer about the dynamic impact of regional market segmentation on the growth and decomposition of of green innovation TFP.The answers to these questions have important policy reference value for the improvement of in China.In view of this,this paper uses the panel data of 30 provinces in China from 2006 to 2017,uses the "relative price method" to measure the three kinds of market segmentation index,and then uses the Super-SBM model and Malmquist index method to measure the change of green innovation TFP in China's provinces under the consideration of"environmental pollution" and its decomposition.Based on the PVAR model,this article measures the impact of the fluctuation of the market segmentation on the growth and decomposition of green innovation TFP.In order to alleviate the endogenous problems in the fixed-effects model,control variables were added to the dynamic panel GMM model to study the dynamic impact of market segmentation on the growth and decomposition of green innovation TFP.Finally,on the basis of the above research,it further proposes a differentiated path and institutional arrangement to regulate market segmentation and improve the green innovation TFP in China.The main conclusions are as follows:(1)From the perspective of market segmentation,the national average and standard deviation of commodity market segmentation,capital market segmentation,and labor market segmentation have all decreased over time,and the market has become unified and stable.The average growth rate of the green innovation TFP is 5.45%;the average growth rate of green innovation technology innovation is 1.44%;and the average growth rate of R&D innovation technology progress is 3.95%.Combining the trend of market segmentation and green innovation total factor productivity growth,we can see that market segmentation has a negative impact on the growth and decomposition of green innovation total factor productivity,and this effect may have time lag and continuity.(2)The results of PVAR show that the impact of the impulse of different market segmentations on the growth and decomposition of green innovation TFP is different in the short,medium and long term.On the whole,the growth and decomposition of green innovation TFP have a positive response to their own impact,reflecting the cumulative effect of innovation level;The cumulative effects of the responses of the growth of green innovation total factor productivity on market segmentation of commodities,capital,and labor in the first ten periods were 1.20%,-1.64%,and 0.43%,respectively;The cumulative effects of the responses of the growth of green innovation total factor productivity on market segmentation of commodities,capital,and labor in the first ten periods were-1.67%,0.89%and 0.43%,respectively;The cumulative effects of the responses of the growth of green innovation total factor productivity on market segmentation of commodities,capital,and labor in the first ten periods were 2.88%,-2.00%,and-0.39%,respectively.(3)The results of the dynamic panel GMM show that the effects of various market segmentations on the growth of green innovation TFP are significant inhibitory effects;The commodity market segmentation and the capital market segmentation inhibited the growth of green innovation technology,while the labor market segmentations promoted the growth of green innovation technology;The various market segmentations have restrained the growth of green innovation efficiency to a certain extent. |
