Do geographically nearby major customers mitigate suppliers’ stock price crash risk?

This study examines the impact of geographically nearby major customers on suppliers' stock price crash risk. Using a sample of Chinese A-share listed firms and their top five (major) customers during the period 2008–2019, we find a significantly negative association. This association is robust in a series of robustness checks, including the use of instrumental variables estimations, propensity score matching procedure, and Heckman two-step sample selection model. The mitigating effect of supplier?customer proximity on crash risk is more pronounced for suppliers with lower corporate transparency and greater operational uncertainty. Finally, we identify two possible mechanisms through which geographically nearby major customers reduce suppliers’ crash risk: fewer financial restatements and higher accounting conservatism of suppliers. The findings of this study indicate that listed firms may choose geographically nearby customers to reduce crash risk.     

Minimum wages and non-listed firm’s earnings management: Evidence from a geographic discontinuity design

We examine how and to what extent minimum wage shapes non-listed firms’ earnings information production. To identify the causality, we introduce an improved geographic information system technique to locate firms in areas that straddle the continuities of county borders and then exploit discontinuities of minimum wage at county borders. We find that firms significantly manage earnings information upward as response to increases in minimum wages, particularly for firms with financial constraints. Our findings shed light on the effects of labor policy on the information production of firms and provide policy implications to regulators concerned with the allocation efficiency of capital markets.     

贸易自由化与企业内的产品质量调整

多产品出口企业是中国出口贸易的重要组成部分。在贸易自由化冲击下,该类企业如何调整其核心产品与非核心产品的生产,对于提升企业乃至整体产业的国际竞争力具有重要意义。本文在异质性企业模型基础上内生化产品质量构建理论模型,并使用中国工业企业数据和中国海关数据对模型进行实证检验。研究发现,中间产品进口关税的下降会促使多产品企业对出口产品的质量进行升级,从而提高出口产品定价,且企业的非核心产品质量提升的幅度相对更高,出口价格上升的幅度也更大,即中间品贸易自由化可以缩小多产品企业内的非核心产品和核心产品的质量和价格差距,从而优化企业内的资源配置。异质性分析发现,对于异质性商品而言,关税下降使企业出口产品质量和出口产品价格变化更大,而同质性产品的质量和价格变化则不明显。本文进行了一系列稳健性检验,结果均支持本文的基本结论。     

集体土地他项权利征收补偿制度研究

研究目的:实现集体土地他项权利征收补偿的法律制度化。研究方法:文献研究法,规范—实证分析法。研究结果:目前,中国集体土地他项权利征收补偿制度是残缺不全的,未能正确反映集体土地他项权利征收补偿中的权利与义务关系的一致性。集体土地他项权利不仅具有对世性的物权效力,而且具有独立的经济价值,在世界许多国家或者地区法中,不动产他项权利都被普遍地纳入了征收补偿的权利范畴。研究结论:有必要在有关规范性文件的制定与修改中,从登记条件要求、实体性制度和程序性制度三方面,建立健全集体土地他项权利征收补偿的法律制度。     

“一带一路”倡议与企业国际化程度——基于制造业上市公司的证据北大核心

本文将“一带一路”倡议视为一项准自然实验,基于2007~2020年A股制造业上市公司数据,运用双重差分模型探究“一带一路”倡议对企业国际化程度的影响。研究发现,“一带一路”倡议能够显著提升企业国际化程度。作用机制研究发现,“一带一路”倡议可以通过缓解融资约束和提升研发强度提升企业国际化程度。异质性检验发现,“一带一路”倡议能够提升大规模企业和中小规模企业国际化程度,且对中小规模企业国际化程度的提升效应更加明显;相对于内向型城市节点,“一带一路”倡议显著提升了外向型节点城市企业国际化程度。进一步地,“一带一路”倡议能够显著促进企业国际化范围的扩张。
