The global value chain has introduced profound changes in international trade, economic development, and technology progress as well as greenhouse gas emissions worldwide. This paper investigated the impact of the global value chain and technological innovation on greenhouse gas emissions by introducing a partially linear functional-coefficient model based on panel data of 15 industrial sectors in China from 2000 to 2020. Moreover, the greenhouse gas emission trends of China's industrial sectors from 2024 to 2035 were predicted using the autoregressive integrated moving average model. The results showed that (1) Greenhouse gas emissions were affected negatively by global value chain position and independent innovation. Nevertheless, foreign innovation had the opposite effect. (2) The results of the partially linear functional-coefficient model implied that the inhibitory effect of independent innovation on GHG emissions decreased with an improvement in the global value chain position. (3) The positive effect of foreign innovation on greenhouse gas emissions increased and then, decreased as the global value chain position improved. (4) The prediction results indicated that greenhouse gas emissions will continue on an upward trend from 2024 to 2035, while industrial carbon dioxide emissions should peak at 10.21 Gt in 2028. This carbon-peaking goal would be achieved in China's industrial sector by actively improving the global value chain position. Addressing these issues will enable China to take full advantage of the development opportunities of participating in the global value chain.
全球价值链在国际贸易、经济发展、技术进步以及全球温室气体排放方面引发了深刻变革。本文基于2000年至2020年中国15个工业部门的面板数据,引入部分线性函数系数模型,研究了全球价值链和技术创新对温室气体排放的影响。此外,运用自回归积分移动平均模型预测了2024年至2035年中国工业部门的温室气体排放趋势。结果表明:(1)温室气体排放受到全球价值链地位和自主创新的负面影响。然而,国外创新的影响则相反。(2)部分线性函数系数模型的结果表明,自主创新对温室气体排放的抑制作用随着全球价值链地位的提升而减弱。(3)国外创新对温室气体排放的积极影响随着全球价值链地位的提升先增加后减少。(4)预测结果表明,2024年至2035年温室气体排放将继续呈上升趋势,而工业二氧化碳排放在2028年应达到峰值102.1亿吨。通过积极提升全球价值链地位,中国工业部门将实现这一碳达峰目标。解决这些问题将使中国能够充分利用参与全球价值链的发展机遇。
