【摘要】：文章探索性地将三阶段DEA模型和超效率SBM模型相结合来测算我国东西地区的碳排放效率,并对东西地区碳排放效率的差异及受科技因素的影响进行了对比分析。结果表明,东西地区受所处的外部环境和运气等随机因素影响,碳排放效率表现出显著差异,剔除环境因素和随机误差的影响后,虽然东部地区的碳排放效率依旧高于西部地区,但其差距明显缩小;其中,RD人员对东部地区碳排放效率的提高有显著正向影响,而RD项目对西部地区碳排放效率的提高有显著促进作用。研究认为,东西地区碳排放效率存在差异的主要原因是科技因素,实现西部地区科技减排的关键在于为西部地区RD项目的立项开通绿色通道,同时鼓励更多高科技人才流向西部地区。
[Abstract]:In this paper, the three-stage DEA model and the super-efficiency SBM model are combined to measure the carbon emission efficiency in the east and west regions of China, and the differences of the carbon emission efficiency between the east and the west regions and the influence of scientific and technological factors are compared and analyzed. The results show that there are significant differences in carbon emission efficiency between eastern and western regions affected by random factors such as external environment and luck, excluding the influence of environmental factors and random errors. Although the efficiency of carbon emission in the eastern region is still higher than that in the western region, the gap is obviously narrowed, and the R D personnel have a significant positive impact on the improvement of the carbon emission efficiency in the eastern region. The RD project has a significant role in promoting the efficiency of carbon emissions in the western region. It is believed that the main reason for the difference in carbon emission efficiency between the east and west regions is the scientific and technological factors. The key to realizing the emission reduction of science and technology in the western region lies in opening a green channel for the establishment of the RD project in the western region. At the same time, encourage more high-tech talents to flow to the western region.
