中文摘要：加快提升绿色科技创新竞争力是实现黄河流域高质量发展的必然需求.在利用纵横向拉开档次法系统评价2009～2020年黄河流域绿色科技创新竞争力的基础上,进一步采用核密度估计和空间马尔科夫链对其时空分布格局和动态演进特征进行深入分析,并借助障碍度模型分析阻碍黄河流域绿色科技创新竞争力提升的主要因素.结果表明:①黄河流域绿色科技创新竞争力整体发展呈现出"衰退期""上升期""再衰期""重振期"4个阶段的"W"型变化趋势,地区间绿色科技创新竞争力的绝对差异有所缩小,但仍具有显著的"梯度"发展特征,黄河流域上、中、下游绿色科技创新竞争力依次递增;②黄河流域不同等级间的绿色科技创新竞争力具有转移"惰性",低竞争力地区面临严重的"等级壁垒",而高竞争力地区则存在"俱乐部趋同"现象,空间溢出效应下,绿色科技创新竞争力转移的"等级锁定"概率有所降低,但仍无法实现跨级跃迁;③黄河流域绿色科技创新竞争力的阻碍因素主要体现在绿色发展不足和成果转化不充分等方面,其中单位GDP能耗、能源消费结构、能源消耗、开放程度和绿色科技论文发表数量是阻碍黄河流域绿色科技创新竞争力提升的主要因素.

外文标题：Spatiotemporal Variation and Obstacle Factors of Green Technology Innovation Competitiveness in Yellow River Basin,China

外文摘要：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.
