产业链融入与企业创新——基于微观企业数据的产业链测度新方法
【摘要】“创新链产业链资金链人才链深度融合”是当前国家的重大战略,不同链之间如何实现深度融合富含理论与实践价值。已有研究中产业链的量化框架较为缺乏,本文尝试使用人工智能技术分布式抓取爱企查、商商查、各地区招投标公告及上市公司年报等中的企业关联信息,依托Acemoglu等以有向图数学理论改良投入产出表的思路,采用深度优先搜索算法构建全产业链图谱数据库,测算产业链的内部关联度、质心度等指标,并测出每个链上企业的产业链融入度,最终构建出一个产业链测度的理论框架与新方法。结果表明,融入产业链能有效激励企业创新绩效,并通过知识溢出、规模经济等产生积极作用。该效应会因链主企业性质、产权性质等呈现出显著异质性,更充分的行业竞争亦能强化产业链的创新效应。本产业链量化框架,可为国家现阶段实施的提高产业链韧性、创新链产业链融合、创新驱动发展等战略提供分析范式与决策参考,具有实践指导意义。

Environmental co-benefits of climate mitigation:Evidence from clean development mechanism projects in China
【摘要】The carbon reduction effects of climate mitigation have received much attention, but less attention has been paid to the co-benefits of climate mitigation such as such as air pollution reduction and related health impacts. This oversight may have led to an underestimation of the broader welfare effects of climatemitigation and thus hindering its progress in implementation. This paper investigates the co-benefits of climate mitigation through focusing on the pollution reduction effects of the implementation of the clean development mechanism (CDM), which is an important climate mitigation mechanism to enhance north-south climate cooperation. Using a unique firm-level dataset with data on China’s CDM projects from 1998 to 2012, we show that the CDM implementation reduced sulfur dioxide emissions. Mechanism analyses show that the CDM implementation alleviated firms’ financing constraints and promoted fossil energy savings, thereby reducing emissions of air pollutants that usually coexist with greenhouse gases in burning fossil fuels. We also find that the CDM didn’t bring about the expected technological progress. These results highlight environmental co-benefits of climate mitigation and provide important implications for international climate cooperation.
