全球价值链嵌入能提升技术进步的节能减排效应吗?——基于中国工业面板数据的实证检验

Can Global Value Chain Embeddedness Improve the Effect of Technical Progress on Energy Conservation and Emission Reduction: An Empirical Study on Panel Data of China's Industries

利用1999-2015年23个工业行业面板数据,测算中国工业行业全要素生产率以及能耗和排放强度,并实证检验技术进步的节能减排效应以及GVC嵌入对偏效应的影响。结果表明:中国工业行业技术水平不断提升,高技术工业明显高于传统工业;工业行业能耗强度和排放强度不断降低,但高能耗、高排放和高投入的"三高"行业并未带来较高的人均产出以及吸纳较多的劳动力。实证检验结果显示,技术进步能够显著推动中国工业行业节能减排,然而GVC嵌入会在技术进步对节能减排的偏效应中产生显著负向作用,但这种负向作用存在行业异质性特征,在技术类行业以及生产者驱动型行业更为显著,而在非技术类行业和购买者驱动型行业并不存在,并且可能转变为正向提升作用。

We use panel data including 23 industries from 1999 to 2015 to measure TFP and the intensity of energy consumption and emission in China＇s industry. Then the effect of technical progress on energy conservation and emission reduction and the influence of GVC on this partial effect are empirically tested. Evidences show that the level of technical progress in China＇s industry has been continuously raised and high-tech industries are obviously higher than traditional industries. In addtion,the intensity of energy consumption and emission are on the decline,while the industries with high energy consumption,high emission and high input have not produced high output per capita and absorbed more labor force. Technical progress can significantly promote energy conservation and emission reduction in China＇s industry. However,global value chain embeddedness has a significant negative influence on the partial effect of technical progress on energy conservation and emission reduction,which has characterstic？ of heterogeneity in different industries. The negative influence is very significant in technical industry and buyer-driven industry,which does not exist in nontechnical industry and producer-driven industry and may translate into positive ascension.
