工业用地市场化配置的降碳效应与作用路径研究

On Carbon Emission Reduction Effect and Pathways of Market-oriented Allocation of Industrial Land

本文探索在碳减排治理新阶段,工业用地要素市场化配置对地区降碳效应的影响,为深化要素市场化配置提供参考。文章基于全国30个省域2009—2020年的碳排放数据,采用双固定模型检验工业用地市场化配置对地区降碳效应的影响及作用机制。结果表明,工业用地市场化配置显著促进地区降碳效应,经过一系列稳健性检验后结果仍然成立;能源强度与能源消费结构低碳化水平对降碳效应产生正向调节作用,强化工业用地市场化配置对降碳效应的促进作用,资本错配会对降碳效应产生负向调节作用,弱化二者之间的促进作用;工业用地市场化配置对降碳效应在北方和低工业化水平地区的促进效应更显著;进一步分析发现,工业用地市场化配置显著抑制地区污染物排放水平,工业用地出让价格扭曲和工业用地出让面积增加均会抑制地区降碳效应,工业用地招拍挂出让方式显著促进降碳效应。为进一步落实碳减排目标,应提高工业用地要素市场化配置程度,充分发挥市场机制,适当弱化政府干预,最大化工业用地市场化配置政策的动态性和延续性对地区长期降碳效应的促进作用。

This paper explored the impact of market-oriented allocation of industrial land factors on regional carbon emission reduction in the new stage of carbon emission reduction governance,thus providing reference for the enhancement of the market-oriented allocation of factors.This paper,based on carbon emission data in 30 provinces of China from 2009 to 2020,employed a double fixed model to examine the impact of market-oriented allocation of industrial land on regional carbon emission reduction and its working mechanism.The results indicated that the market-oriented allocation of industrial land had significantly promoted the regional carbon emission reduction and the results held true after plenty of robust testing.Energy intensity and the low-carbon level of the energy consumption structure had a positively moderating effect on the carbon emission reduction which would reinforce the promotion effect of market-oriented allocation of industrial land on carbon emission reduction while capital misallocation had a negatively moderating effect on the carbon emission reduction which would weaken the promotion effect between them.The promotion effect of market-oriented allocation of industrial land on carbon emission reduction was more significant in northern China and regions of low industrialization;What’s more,further analysis revealed that the market-oriented allocation of industrial land had significantly restrained the level of regional pollutant emissions,as well as distorted industrial land transfer prices and increased industrial land transfer areas would both inhibit the regional carbon emission reduction effect,while the methods of auction,bidding and listing for industrial land transfer significantly played an enhanced role in this aspect.To further implement the carbon emission reduction goals,it was advisable to increase the degree of market-oriented allocation of industrial land factors,fully leverage market mechanisms to moderately weaken government intervention,and maximize the promotion effect of dynamic and continuous market-oriented allocation policies of industrial land on long-term regional carbon emission reduction effect.
