随着对外开放程度的不断扩大,中国与其它国家之间的贸易往来也在不断加强。国际贸易技术溢出能够促进一国生产率和技术进步的提高已被诸多学者所证实。运用基于投入导向的规模报酬不变的DEA模型测算中国各地区的全要素能源效率,并基于国际贸易视角检验技术溢出对全要素能源效率的影响,结果显示国际贸易技术溢出促进了中国各地区全要素能源效率的提高。
With the continuous expansion of the opening up to the outside world, the trade between China and other countries is also constantly strengthening. It has been confirmed by many scholars that the technology spillover of international trade can promote the productivity and technological progress of a country. Using input-oriented DEA model with constant returns to scale to calculate total factor energy efficiency in various regions of China and examining the impact of technology spillover on total factor energy efficiency based on the perspective of international trade, the results show that technology spillover from international trade has promoted the development of all regions in China Elemental energy efficiency improvement.
