要素市场扭曲对工业绿色创新的直接影响及空间溢出效应

要素市场改革和技术创新是促进经济高质量发展的重要举措,两者间的关系是学术界关注的重点。研究表明,市场化进程和工业绿色创新在省域间都具有空间关联性而并非随机分布。利用动态空间杜宾模型并结合偏微分方程的实证研究表明,各区域工业绿色技术创新具有内在的惯性及自我扬弃特征,前期创新积累对当期的创新进程具有动态影响。从全国范围考察,要素市场扭曲对各区域本地工业绿色创新存在明显抑制效应,且长期效应超过短期效应。相对发达与欠发达地区各自在要素市场扭曲互动策略上的差异性致使本地要素市场扭曲对外地工业绿色创新反而存在正向间接影响即外溢效应。从分区域层面考察,东部沿海各省区其要素市场扭曲程度要明显弱于中西部地区,其对域内工业绿色创新的抑制效应相比中西部地区要小。

Research on the Direct Influence and spatial Spillover Effect of factor Market Distortion on Industrial Green Innovation

Factor market reform and technology innovation are important measures to promote high-quality economic development. Their relationship is the analysis focus of academic circles. Studies have shown that the marketization process and industrial green innovation are spatially related in the provincial interval and not randomly distributed. The empirical research using dynamic space Durbin model combined with partial differential equations shows that the industry green innovation has inherent inertia and self-sublation characteristics. The early innovation accumulation has a dynamic impact on the current innovation process. From a nationwide perspective, factor market distortions have significant inhibitory effects on local industry green innovation in various regions, and long-term effects exceed short-term effects. The differences in factor market distortion interaction strategies between the relatively developed and underdeveloped regions have caused a positive and indirect impact on the green innovation of other regions. From the sub-regional level, the factor market distortion in the eastern coastal provinces is significantly weaker than that in the central and western regions, and its suppression effect on the industry green innovation is smaller.
