【摘要】：国际间的技术溢出是缩小国家间差距的主要方式,一国的技术进步既取决于国内的研发投入,也取决于国外研发活动溢出的影响。一国可以通过进口贸易获取先进国家高质量的产品,并对物化其中的技术学习、消化和吸收,促进本国技术进步,而技术进步对碳减排的作用也日益成为各方关注的焦点。中国是二氧化碳排放第一大国,碳减排成为我国目前亟待解决的问题之一。虽然我国对低碳减排技术越来越重视,但由于我国起步较晚,技术水平和设备较为落后,对碳减排不能发挥技术效应,因此重视发达国家的技术经验的引进是我国目前低碳技术研发的重要途径。目前有关碳减排的研究中,几乎忽视了物化在进口贸易中的先进技术,进口国可以通过对先进技术的学习、消化和吸收,产生进口贸易技术溢出效应,及其对进口国碳排放强度的影响。基于此考察进口贸易技术溢出对我国碳排放的影响具有重要意义。基于以上背景,本文应用LP方法测算30个省市自治区2000-2014年间从G7国家进口贸易中获得的技术溢出效应,分析进口贸易技术溢出的地区差异,同时基于省际面板数据从吸收和引进两方面分析影响进口贸易技术溢出的因素。在此基础上,考虑空间相关性,从进口贸易技术溢出视角,结合进口贸易技术溢出的吸收能力,构建碳排放强度影响因素分析空间面板模型,并将进口贸易技术溢出对碳排放强度的空间影响分解为直接效应和间接效应。研究成果表明:(1)我国30个省市通过进口从G7国家获得的贸易技术溢出总体呈增加的趋势,分布上呈现由东部向中西部递减的趋势,且区域分布差异明显;(2)研发强度、人力资本和贸易结构对我国进口贸易技术溢出起正向促进作用,技术差距起负向抑制作用;(3)我国省际间碳排放强度存在显著的空间正相关性,省际碳排放强度趋于集中;(4)进口贸易技术溢出对我国碳排放强度产生抑制作用,空间相关性使得进口贸易技术溢出对周边省份碳排放强度的间接效应显著大于对本省碳排放强度的直接效应;(5)研发强度和人力资本没有很好地传导与扩散进口贸易技术溢出对碳排放强度的抑制作用。
[Abstract]:International technology spillover is the main way to narrow the gap between countries. The technological progress of a country depends not only on domestic R & D investment, but also on the impact of foreign R & D spillover. A country can acquire high quality products from advanced countries through import trade, and learn, digest and absorb the technology of materialization, and promote its own technological progress, and the effect of technological progress on carbon emission reduction has become the focus of attention. China is the largest country in carbon dioxide emissions, carbon emission reduction has become one of the problems to be solved. Although China pays more and more attention to low-carbon emission reduction technology, due to its late start and backward technology level and equipment, it can not play a technological effect on carbon emission reduction. Therefore, to attach importance to the introduction of technological experience of developed countries is an important way of low-carbon technology R & D in China. At present, in the research on carbon emission reduction, the advanced technology of materialization in import trade is almost ignored. The importing country can learn, digest and absorb the advanced technology to produce spillover effect of import trade technology. And its impact on carbon emission intensity in importing countries. Based on this, it is of great significance to investigate the impact of import trade technology spillover on carbon emissions in China. Based on the above background, this paper uses LP method to estimate the technology spillover effects from the import trade of G7 countries in 30 provinces, cities and autonomous regions from 2000 to 2014, and analyzes the regional differences of technology spillovers in import trade. At the same time, based on the interprovincial panel data, the factors affecting technology spillover of import trade are analyzed from two aspects of absorption and import. On this basis, considering the spatial correlation, from the perspective of import trade technology spillover, combined with the absorption capacity of import trade technology spillover, the paper constructs a spatial panel model of carbon emission intensity influencing factors. The spatial effect of import trade technology spillover on carbon emission intensity is divided into direct effect and indirect effect. The research results show that the trade technology spillovers from the G7 countries obtained by 30 provinces and cities in China through import are on the whole increasing, and the distribution is decreasing from the east to the central and western regions, and the regional distribution is obviously different in terms of R & D intensity. Human capital and trade structure play a positive role in promoting technology spillover of China's import trade, and the technology gap plays a negative role in restraining it. (3) there is a significant spatial positive correlation between China's inter-provincial carbon emission intensity. Inter-provincial carbon emission intensity tends to be concentrated. (4) Technology spillovers from import trade have a restraining effect on China's carbon emission intensity. Spatial correlation makes the indirect effect of technology spillover of import trade on the intensity of carbon emissions in neighboring provinces is significantly greater than the direct effect on the intensity of carbon emissions in the province. 5) R & D intensity and human capital are not well conducted and diffused in import trade. Easy technology spillover to restrain carbon emission intensity.
