Accelerating the enhancement of green technology innovation competitiveness is an inevitable requirement for achieving high-quality development in Yellow River Basin.Building upon a systematic evaluation of the green technology innovation competitiveness in Yellow River Basin from 2009 to 2020,using vertically and horizontally opening grade method,an in-depth analysis of its spatiotemporal distribution pattern and dynamic evolution features was further conducted through the utilization of kernel density estimation and spatial Markov chain;additionally,an obstacle degree model was employed to analyze the main factors hindering the improvement of green technology innovation competitiveness in Yellow River Basin.The results show that ① the overall development of green technology innovation competitiveness in Yellow River Basin exhibits a"W"-shaped trend with four stages,including decline period,ascendancy period,re-decline period,and revitalization period;the absolute differences in green technology innovation competitiveness between regions have diminished,yet a significant gradient development characteristic persists,with competitiveness increasing successively from upstream to downstream.② There is a transfer inertia of green technology innovation competitiveness between different levels in Yellow River Basin;regions with low competitiveness face severe grade barriers,while regions with high competitiveness exhibit a club convergence phenomenon;under spatial effects,the probability of grade locking in the transfer of green technology innovation competitiveness decreases,but cross-level transitions remain elusive.③ The obstacles to green technology innovation competitiveness in Yellow River Basin mainly manifest in the aspects of inadequate green development and outcome transformation;factors such as unit GDP energy consumption,energy consumption structure,energy consumption,openness,and the number of green technological papers published are identified as the primary impediments to the enhancement of green technological innovation competitiveness in Yellow River Basin.
