青藏高原地区绿色全要素生产率时空分异与驱动机理

Spatio-temporal Variation and Driving Mechanism of Green Total Factor Productivity in the Qinghai-Tibet Plateau Region

提高绿色全要素生产率是促进青藏高原地区经济社会高质量发展的重要举措。基于2000~2019年青藏高原地市州面板数据,综合运用全域Malmquist-Luenberger指数、非参数Kernel核密度估计、空间马尔科夫链和面板分位数回归等方法,分析青藏高原地区绿色全要素生产率的时空演化特征及其驱动机理。结果表明:(1)研究期内,青藏高原地区绿色全要素生产率的演化趋势相对稳定,在省区和地市州层面上均波动起伏,上下徘徊,呈现“多峰”波浪型集聚形态;(2)青藏高原地区地市州绿色全要素生产率空间分异的连续性和稳定性良好,在空间上存在跨越式转移的可能,并在连续转移过程中存在“马太效应”;(3)经济发展水平、产业结构和人口规模均能在不同水平上促进青藏高原地区绿色全要素生产率的提升,而城镇化进程的加速不利于绿色全要素生产率的增长。

Improving green total factor productivity(GTFP)is an important initiative to promote high-quality economic and social development in the Qinghai-Tibet Plateau region.Based on the panel data of cities in the Qinghai-Tibet Plateau from 2000 to 2019,the spatial-temporal evolution characteristics of GTFP and its driving mechanism were analyzed by applying global Malmquist-Luenberger index,non-parametric Kernel density estimation,spatial Markov chain and panel quantile regression.The results showed that:(1)During the study period,the evolution trend of GTFP was relatively stable,with fluctuation at the provincial and city levels,showing a"multi-peak"wave-shaped agglomeration pattern.(2)The spatial differentiation of GTFP had good continuity and stability.There was a possibility of leapfrog transfer in space,and the"Matthew effect"existed in the process of continuous transfer.(3)The level of economic development,industrial structure and population size all promoted the improvement of GTFP in the Qinghai-Tibet Plateau at different levels,while the acceleration of urbanization was not conducive to the growth of GTFP.
