Abstract:This paper takes land price distortion as the starting point,focusing on maintaining sustained and stable economic growth and achieving the “dual carbon” goal to deeply clarify the transmission mechanism of land price distortion on GTFP in theory. Based on the panel data of China's prefecture level cities from 2005 to 2019,this paper uses static and dynamic panel models to verify the direct impact of land price distortion on GTFP;uses the mediating effect to test the indirect impact of green innovation capability on GTFP;studies the spatial heterogeneity of the impact of land price distortion on GTFP in different cities by sub samples. Research has found that land price distortion significantly suppresses GTFP through green innovation capabilities,and its impact on GTFP exhibits spatial distribution characteristics of insignificant distortion in the eastern region and significant negative distortion in the central and western regions. The research results provide new ideas and empirical evidence for revealing the relationship between land price distortion and GTFP,and designing and improving relevant policies based on this.

一、引 言
自2011年經濟合作發展組織(OECD)首次提出綠色發展是謀求經濟增長的解決方案以來,各國對經濟的綠色發展越來越重視[1-2]。“十四五”規劃強調“推動綠色發展,促進人與自然和諧共生”。經濟綠色發展的關鍵在于如何提升以城市為主體的綠色全要素生產率(以下簡稱“GTFP”)。如何對GTFP進行科學評價,厘清其背后的驅動因素及傳導機制,是該研究領域所面臨的重要現實問題和理論課題。
在我國經濟由高速增長階段轉向高質量發展階段的背景下,要素投入式的經濟發展模式已不可行。因此,提升城市GTFP的核心是充分發揮市場在資源配置中的決定性作用,提高資源配置效率是當前及今后提升GTFP水平的重要手段。……
