How Double-Carbon Policies Affect Green Technology Innovation Capability of Enterprise: Empirical Analysis Based on Spatial Dubin Model
利用2011-2020年中国30个地区数据，通过空间杜宾模型分析双碳政策强度、政府资助、大数据发展对企业产品型和过程型绿色技术创新能力的影响，发现政策强度有正向直接效应和负向空间溢出效应。
Double-carbon policies are crucial for governments to steer corporate transformation toward green tech innovation and high-quality economic growth. Using data from 2011 to 2020 across 30 Chinese regions, this study constructs a spatial Dubin model to explore links among double-carbon policy intensity, government funding, big data development, and product/process-oriented green tech capabilities in firms. The results show that the intensity of double-carbon policies has a significantly positive impact on product-oriented and process-oriented green technology innovation capabilities of enterprises. The intensity of double-carbon policies has a significantly positive and direct effect but a negative spillover effect on process-oriented green technology innovation capability of the enterprise, whereas it only has a significantly positive and direct effect on the product-oriented green technology innovation capability of the enterprise. Government funding support mediates the effect of the intensity of double-carbon policies on product-oriented and process-oriented green technology innovation capabilities of enterprises. Big data development level moderates the effect of government funding support as a mediator on the product-oriented green technology innovation capability of the enterprise, but cannot moderate the effect of the intensity of double-carbon policies on the product-oriented green technology innovation capability of the enterprise.
