摘要
出口企业立足国内国际市场,紧随全球低碳发展趋势,紧贴国际绿色技术前沿,具备开展绿色创新的内在动力和技术资源,在低碳城市试点政策的约束与推动下,可能表现出更为活跃的创新意识与更加积极的创新行为。然而,现有研究大多忽视“出口-非出口”这一异质性视角,导致对于低碳城市试点政策的评估缺乏开放性维度。为此,该研究基于2004—2020年沪深两市A股出口上市公司的绿色专利申请数据,采用多期双重差分模型实证检验低碳城市试点政策对于中国出口企业绿色创新的影响,梳理其中的作用机制,并从所有制属性、污染程度、技术水平等多个维度开展异质性分析。结果表明:①低碳城市试点政策有效地激发了出口企业的绿色创新行为,实现了创新数量、创新质量和创新效率的同步提升。②与非出口企业相比,低碳城市试点政策对于出口企业绿色创新行为的正向激励效应更加显著。③低碳城市试点政策对于出口企业的绿色创新激励效应主要体现在非国有出口企业层面,对于国有出口企业的影响并不显著,同时该绿色创新激励效应在重污染出口企业与高新技术出口企业层面表现得更加显著。④低碳城市试点政策主要通过研发资金投入增加机制和海外业务拓展机制推动出口企业开展绿色创新。鉴于此,中国政府应继续优化低碳城市政策并“因地制宜”地扩大试点范围,同时要积极探索鼓励出口企业绿色创新的举措,如开展精准补贴,发展绿色贸易,加强国内外环境标准的对接等。
Focusing on both domestic and foreign markets,export firms tend to follow the global low-carbon development trend and get closer to the technological frontier of the world,thus having the motivation and technical advantages to carry out green innovation.Under the regulation and stimulation of the low-carbon city pilot policy,export firms may get involved in innovation activities more actively and intensively in comparison with non-export firms.However,few studies have noticed this tendency,which leads to an incomplete assessment of the low-carbon city pilot policy,especially from an open perspective.Using the green patent application data of export-oriented listed firms in China from 2004 to 2020,this paper used the difference-in-differences model to examine the impact of the low-carbon city pilot policy on export firms’green innovation and further analyzed the intermediate mechanism and heterogeneity.The study found that:①The low-carbon city pilot policy significantly induced the green innovation activities of export firms,and realized the synchronous improvement of innovation quantity,quality,and efficiency.②The green innovation incentive effect of the pilot policy was more significant for export firms compared with non-export firms.③The pilot policy showed a greater incentive effect on non-stateowned export firms,polluting export firms,and high-tech export firms.④The low-carbon city pilot policy mainly promoted export firms to carry out green innovation through the mechanisms of increasing R&D investment and expanding overseas business.In view of this,the Chinese government should expand the scope of the pilot policy according to local conditions.At the same time,the government needs to explore measures to encourage export firms’green innovation,such as implementing more targeted subsidies,developing green trade,and promoting the integration of domestic and international environmental standards.
