本文以沪深两市上市公司为研究对象，以2015年《环境保护法》实施和2005–2016年地方环保法规颁布或修订作为自然实验，从股票市场异常波动角度，考察环境立法对投资者利益保护的影响及其内在机制。研究发现，相对于非重污染企业，环境立法显著增加了重污染企业的行为约束，降低了其股价崩盘风险。从作用机制看，环境立法促使重污染企业增加环保投资，提升环境信息披露质量，且环保投资更多、环境信息披露质量更好的重污染企业股价崩盘风险下降更明显。本文表明，环境立法对公司价值的影响不简单对应于股价涨跌，而是重点体现在降低股价异常波动；环境法规的完善不仅促使企业更好地履行环保责任，而且有利于保护投资者利益和维护资本市场稳定。

From the perspective of pragmatic tolerance, this study investigates L1-Mandarin Chinese L2-English speakers’ derivation of scalar implicatures, with a focus on L2 speakers’ pragmatic tolerance when facing a violation of pragmatic principle. Results from a graded judgment task show that L2 speakers have native-like pragmatic tolerance of underinformative sentences. More importantly, this pragmatic tolerance does not differ between L2 speakers’ native and second languages. This study aims to provide insight for experimental design in semantics-pragmatics research, as well as for second language acquisition of scalar implicatures.

Yang M, Xia X, Zhou Y. Abandoned children in China: the son-preference culture and the gendered-differentiated impacts of the one-child policy. Humanities & Social Sciences Communications [Internet]. 2023;10(532):1-10. 访问链接Abstract
China has experienced an upsurge in child abandonment since the late 1970s in parallel with its one-child policy (OCP) and market reforms. Due to the scarcity of individual-level data, the literature focuses on informal adoption and child trafficking. This study first demonstrates the spatial-temporal trends of child abandonment across over 100,000 self-reported cases spanning 40 years in China collected from an internet platform. We then examine how the OCP and the long-established clan culture influence the incidence of child abandonment at the provincial level. We further compare whether the influences vary across genders. The results indicate that a tougher OCP penalty increases child abandonment, particularly the abandonment of girls. The influence of the OCP on girl abandonment is weaker in provinces with a strong clan culture, where sex ratios at birth are more unbalanced due to an increased incidence of gender-selective abortions.
