水信息披露、机构投资者异质性与企业价值——来自我国A股制造业上市公司的经验证据

以我国2011-2016年A股制造业上市公司为研究样本,本文采用面板回归模型实证检验了企业水信息披露对企业价值的影响以及异质机构投资者在二者关系中的调节作用。结果表明：目前企业水信息披露水平整体较低,其对企业价值有显著的负向影响;在该影响中,机构投资者整体有显著的正向调节作用,压力抵制型机构投资者有显著的负向调节作用,而压力敏感型机构投资者无显著的调节作用。

谁的乡村建设？——基于乡村建筑变迁的观察和思考

在全面推进乡村振兴的大背景下，乡村建设正如火如荼地开展。其中，乡村建设中农民房屋建筑类型从特质性的“匠心独具”到同质性的“千村一面”，再到异化性的“自厝同异”变迁路径，反映出传统文化的保护危机，也深刻揭示出建筑变迁背后暗藏的农民与地方政府间的多元矛盾和博弈。此问题的根源在于农民主体性被消解，成了被建构的对象或客体，而地方政府却不断强化构建主体的身份认同。事实上，当前乡村建设呈现出五种不同的价值取向：一是为城市消费者休闲情趣的乡村建设；二是为城市中产阶级家乡情感的乡村建设；三是为地方政府凸显政绩的乡村建设；四是为开发商投资回报的乡村建设；五是为农民生存利益的乡村建设。不同参与者均带着不同的利益诉求介入乡村建设，直接影响到乡村建设的发展走向。因此，要处理乡村建设中的矛盾和问题，必须强化农民在乡村建设中的主体意识和主体身份，赋予农民对乡村建设事务的话语权与决定权。

投资组合动态VaR预测模型和预测精度评价

采用4种Backtesting检验方法,检验22个常态和时变投资组合动态VaR预测模型的风险预测精度,发现GJR_GPD_TV_Copula具有最高的投资组合风险预测精度,GJR_GPD_Copula的拟合、密度预测和组合风险预测精度都要高于GJR_SKST_Copula,且Copula模型的组合风险预测精度分别与拟合精度和密度预测精度存在较弱的正相关关系.     

Crossing borders with social media: Online social networks and FDI

Social media is embedded in today's internationalization strategy. Companies extend their reach into foreign countries by posting and tweeting. Firms also enhance their mobile capabilities in foreign markets (e.g., knowledge and reputation) through user-generated content in online social networks. Levering on the capabilities-based theory of the multinational enterprise, this paper builds upon a resource-based, industry/network-based, and institution-based view framework. The study provides a comprehensive conceptual and empirical model to explain the effect of social networks on foreign direct investment. Empirical analysis in a global panel dataset of >4500 multinational enterprises suggests that online social networks' activity stimulates foreign capital expenditure and new affiliates. In addition, the article explores the relevance of customer capabilities along with sectoral and institutional moderating effects.     

Why do participants in voluntary organizations leave? Exploring the relationship between value congruence and length of stay

Recognizing the importance of values and the specific characteristics of participants and situations in voluntary organizations, we examine how value congruence—the fit or compatibility of values between participants and the organization, or among participants—interacts with personal and situational factors to predict participants' length of stay in their organizations. Introducing the case of a voluntary organization that offers shared housing, we measure value congruence through textual similarity in the self‐introduction documents of 49 participants and the organization's mission statement. This approach differs from the self‐reported measures based on participants' perceptions or recalled interactions used in previous studies. In line with expectation‐disconfirmation theory, participants with the strongest beliefs in organizational values had shorter lengths of stay. The amount of intraorganizational communication also moderated the relationship between value congruence and length of stay. This study provides theoretical and methodological implications for nonprofit management by considering personal and situational factors and evaluating value congruence by textual similarity.
