不同来源技术进步与二氧化碳排放效率——基于空间面板数据模型的实证

Different Sources of Technology Progress and CO_2 Emission Efficiency——An Empirical Analysis Based on Spatial Panel Data Model

本文以IPAT和STIRPAT模型为理论基础,运用空间面板数据模型考察自主创新、FDI和国际贸易等不同来源技术进步对中国省区层面二氧化碳排放效率的影响.利用超效率SBM模型测算得到1995—2012年中国省区层面二氧化碳排放效率,其中资本、劳动力和能源为投入要素,二氧化碳排放量为非期望产出,GDP为期望产出.研究结果表明:作为技术进步的重要来源,FDI能够显著提高二氧化碳排放效率;由于存在显著的负向空间溢出效应,自主创新和进口对于提升二氧化碳排放效率具有显著的抑制作用;出口对于二氧化碳排放效率的抑制作用不显著.

It used spatial panel data model to investigate the effects of different sources of technology progress,including independent innovation,foreign direct investment,and international trade,on carbon dioxide emissions efficiency at provincial level with IPAT and STIRPAT model as the theoretical basis. It measured the carbon dioxide emissions efficiency at provincial level in China based on the super SBM model in which carbon dioxide emissions as undesirable outputs and GDP as desirable outputs,capital,labor and energy as three input factors from 1995 to 2012. The results indicate that： foreign direct investment as the important source of technology progress can significantly improve the carbon dioxide emission efficiency; independent innovation and import can significantly hinder the carbon dioxide emission efficiency because of significant negative spatial spillovers; export has no significant effect on the carbon dioxide emission efficiency.
