Analysis of Carbon Emission Efficiency in the Yellow River Basin in China: Spatiotemporal Differences and Influencing Factors

A good grasp of the carbon emission efficiency (CEE) provinces in Yellow River basin (YRB) China, and its influencing factors, can help promote sustainable development region smooth realization national reduction target. Based on stochastic frontier analysis (SFA), this paper calculates CEE nine YRB from 2005 to 2019, then, analyzes spatial temporal characteristics. The Durbin model (SDM) with two-way fixed effects is selected investigate factors YRB. results suggest that: (1) overall shows a slow upward trend, although gap between large, it slowly narrowing; (2) there significant negative autocorrelation YRB; (3) technological innovation capability, energy consumption structure, population density, urban greening level are most affecting Both density have positive effect improvement themselves whole YRB, also spillover due density. Technological capability structure had impact province during research period. This study may some reference value for improving
