中国经济学的进步离不开经济学期刊的支撑和引导,近年来中国的经济学期刊纷纷引入国际通行的匿名审稿制度,这一制度变革是否促进了中国的经济学进步?中国经济学期刊采用匿名审稿制度的差异性为我们提供了一个“准自然实验”,本文首次采用中国经济管理类366种期刊2003—2012年的面板数据,利用影响因子、总被引频次、平均引文率、被引半衰期、立即指数等五个指标,就匿名审稿制度对中国经济学学术进步的推动作用进行系统评价。在采用双重差分方法(Difference in Differences)并进行了一系列稳健性检验后发现,匿名审稿制度的推行使得学术期刊的影响因子、总被引频次、平均引文率显著上升,事实匿名审稿制度比名义匿名审稿制度的作用更强。而且,匿名审稿制度的推行具有动态效应,随着推行年份的延长,学术进步越为明显。一方面,这一发现为推动中国经济学进步提供了一个重要的制度变革依据;另一方面,在中国学术期刊竞争日益激烈的背景下,这一发现对中国的学术期刊提高期刊竞争力和影响力具有重要的借鉴意义。
供应链数字化转型是从产业生态层面助力“双碳”目标实现的重要契机。基于2018年启动的“供应链创新与应用”试点项目,以2012~2022年沪深A股上市公司数据为研究样本,通过双重差方法检验供应链数字化对企业ESG表现的影响效应和异质性表现。研究发现:供应链数字化显著改善了企业环境、社会和治理(ESG)表现,经一系列稳健性检验后结论依旧成立。异质性检验发现:供应链数字化的成效会因为企业所处的内外部环境和供应链结构特征的不同而产生差异。非国有企业、供应链运营环境欠佳的企业和供应链集中度较低的企业中,供应链数字化对ESG表现的改善作用更明显。The digital transformation of supply chain is an important opportunity to help achieve the goal of “double carbon” at the level of industrial ecology. Based on the pilot project “Supply Chain Innovation and Application” launched in 2018, the study examines the effects of supply chain digitization on corporate ESG performance and the heterogeneity of corporate ESG performance through the double-difference method using the data of A-share listed companies in Shanghai and Shenzhen from 2012 to 2022 as the research sample. The study finds that supply chain digitization significantly improves corporate environmental, social and governance (ESG) performance, and the conclusion still holds after a series of robustness tests. The heterogeneity test finds that the effectiveness of supply chain digitization varies according to the internal and external environments of the firms and the structural characteristics of the supply chain. The improvement of ESG performance by supply chain digitization is more pronounced among non-state-owned enterprises, enterprises with poor supply chain operating environments, and enterprises with lower supply chain concentration.
