中国嵌入全球价值链对绿色技术创新的影响

在对全球价值链嵌入影响绿色技术创新特质、机理、异质性、滞后性与动态效应进行理论分析的基础上，运用2008-2018年中国内地25个省份面板数据，测度中国各省份全球价值链嵌入对绿色技术创新的影响。结果发现：(1)从全国层面看，绿色技术创新是一个动态演化、循序渐进的过程，嵌入全球价值链对绿色技术创新具有显著促进作用，但这种影响存在逐渐减弱的滞后性；(2)从时间层面看，嵌入全球价值链对绿色技术创新的影响具有显著时间差异性，伴随着中国自主创新水平提升和环境规制力度加大，以及发达国家逆全球化趋势盛行，近年来嵌入全球价值链对绿色技术创新的影响日渐减弱；(3)从地区层面看，嵌入全球价值链对绿色技术创新的影响具有显著地区差异性，中西部地区嵌入全球价值链对绿色技术创新的影响比东部地区更明显。据此，提出进一步优化全球价值链嵌入度、扩大全球价值链溢出效应、缩小不同地区间技术差距等政策建议。

The Impact of China′s Embeddedness in the Global Value Chain on Green Technology Innovation

With the deepening of opening to the world, China'sembeddedness in the global value chains has been continuously improved. At present, China is one of the country deeply embedded in the global value chain. It is undeniable that China has fully enjoyed the dividends brought by integrating into the global economy, and has witnessed rapid economic growth. However at the beginning of reform and opening up, due to the constraints of relative surplus of labor factors, relatively insufficient supply of capital factors, China could only integrate into the global value chain in the way of"low-end embedding",andthere is a big gap between China and developed countries in terms of resource endowment and technical capabilities. The transfer of low value-added production to China has led to a series of environmental pollution problems. Under the background that all countries in the world regard green technology innovation as an important means to achieve economic growth and ecological environment synergy, this paper discusses whether China's embedding in the global value chain has impacted on green technology innovation, and how China's green technology innovation has been affected by different regions and different periods of time, which is of great significance for China to continue to embed in the global value chains both at present and in the future, and meanwhile carry out green technology innovation to achieve a win-win situation between economic growth and environmental protection.#br#On the basis ofthe theoretical analysis of the characteristics, mechanisms, heterogeneity, lag and dynamic effects of global value chain embeddedness affecting green technology innovation, this paper uses the panel data of 25 provinces from 2008 to 2018 to measure their GVC embeddedness, and studies the impact of global value chain embeddedness on green technology innovation. The main conclusions are as follows. (1) From the national level, green technology innovation is a dynamic evolution and a step-by-step process. Embedding the global value chain has a significant role in promoting green technology innovation, but there is a gradual weakening lag effect. (2) From the perspective of time, there are obvious time differences in the impact of embedding in the global value chain on green technology innovation. With the improvement of China's independent innovation level and the strengthening of environmental regulations, as well as the trend of anti-globalization in developed countries, the influence of global value chains embeddedness on green technology innovation is gradually weakening recently. (3) From a regional perspective, there are obvious regional differences in the impact of embedding global value chains on green technology innovation. The impact of embedding global value chains in central and western regions on green technology innovation is more important than that in eastern regions. According to the impact of GVC embeddedness on green technology innovation, it is necessary for China to further optimize policies to increase GVC embeddedness, amplify the spillover effects of embeddedness in GVCs, and reduce technological imbalances among different regions.#br#There are some marginal contributions of this research. First, it expands the pure knowledge spillovers result from embeddeding in the general network to the international knowledge and technology spillovers result from embeddeding in the global value chain focusing on the international division of labor within products, and analyzes the characteristics and mechanisms of global value chain embedding affecting green technology innovation. This theoretical innovation has laid a solid foundation for in-depth analysis of the impact of GVC embedding on green technology innovation; the second is to incorporate various factors affecting green technology innovation into the analytical framework of GVC embedding affecting green technology innovation, it also analyzes GVC embedding on green technology innovation and the impact of other factors on green technology innovation. The innovation in this analytical framework makes the conclusion that GVC embedding affects green technology innovation more scientific; thirdly, the overall situation of the impact of China's global value chain embeddedness on green technology innovation is analyzed by time and space heterogeneity, which confirms the reality that China's global value chain embeddedness affects green technology innovation,so that the analysis is more comprehensive.#br#
