国际性绿色技术溢出与我国技术进步

绿色技术是突破经济增长中资源环境制约的关键要素。本文基于吸收能力视角对CH模型进行了修正,并以2000-2011年我国29个地区为对象,测度了国际贸易中G7国家的绿色技术溢出效应。从全国和地区两个维度对比了绿色技术自主创新、国际溢出与省域溢出效应对全要素生产率、技术变动和效率变动的影响。经验研究表明,全国层面上,省域间绿色技术溢出的促进效应最为显著。地区层面上,东部以自主创新和接受国际溢出为主,中部地区跨区域溢出效应最显著,西部地区技术的提升主要依赖于区域间溢出。最后根据研究结论,对地区绿色技术的发展提出政策建议。

International green technology spillovers and China's technical progress

Green technology is important to break through the restriction on resources and environment problems in economic growth. In this paper, the CH model is modified from the perspective of absorptive capacity. Using the data of 29 regions in China during 2000-2011, the green technology spillover from G7 countries is estimated. Meanwhile, the impacts of green technology innovation, international spillover and inter-provincial spillover on total factor productivity, technical and efficiency changes are compared from two different perspectives. An empirical research shows that, at the national level, inter-provincial spillovers' stimulative effect is the most significant. At the regional level, the Eastern Region mainly adopts independent innovation and the international spillovers. The most significant way in the Central Region is to absorb the inter-provincial spillovers. And in the Western Region, the technological progress mainly depends on the regional overflows. Finally, according to the above conclusions, some policy suggestions on green technology development are proposed.
