中国邮政储蓄制度变迁：历史与趋势

邮政储蓄自恢复以来得到了迅速发展，但其负外部性逐渐凸现，从而影响到了中国经济发展的整体结构和金融体系的正常秩序。邮政储蓄制度改革已成为中国金融体系改革所关注的焦点之一，问题的产生在于背后的制度因素，制度变迁应该是改革邮政储蓄机构的根本路径。就邮政储蓄制度的现实而言，机构银行化是一个取向，但也并非一蹴而就，而表现为一个过程。改革推动者应该遵循整体利益大于制度成本的原则设计制度安排．

Short Positions in the First Principal Component Portfolio

Insurance companies and pension plans typically hold well-diversified equity portfolios. These institutions are also often restricted from taking short positions. The diversification requirement operates on the portfolio level, while the short sale constraint is at the individual security level. We examine an investment strategy that exposes a tension between these two requirements. This strategy uses the first principal component to construct the portfolio and by design meets the first requirement. Empirical portfolios based on the first principal component do an excellent job of capturing market exposure and minimizing diversifiable risk. However, in practice such portfolios sometimes contain a few short positions. So this strategy does not always meet the second requirement. We examine which features of stock returns give rise to short positions when a portfolio is based on the first principal component, and we are able to identify the characteristics of the stocks that are responsible for the short positions. These stocks tend to have negative correlations with the majority of other stocks. In contrast such stocks would typically be held long in a Markowitz portfolio. We discuss and explain this puzzle.     

Do environmental regulations hamper small enterprises' market entry? Evidence from China

Due to the serious increase of environmental pollution in China, environmental regulations have become significantly stringent. Such regulations are playing an increasingly important role in the development of small enterprises (SEs) in China, especially in SEs' market entry. However, existing studies pay little attention to this issue. This paper investigates for the first time the effect of environmental regulations on SEs' market entry and the mechanism of environmental regulation effects in China. We consider two sets of panel data for the periods 2003–2010 and 2012–2015 in China. We also use the fixed effect model and the instrumental variable method to explore the role of environmental regulations in SEs' market entry. The results show that, overall, environmental regulations play a significantly positive and robust role in SEs' market entry. However, the mechanisms associated with the effect of environmental regulations on different innovative types of SEs differ. Environmental regulations promote the market entry of SEs with product innovation, but this impact is not significant for SEs with research and development (R&D) activities and R&D institutions. Our findings indicate that China's SEs prefer product innovation, which is a lower level innovative type, over R&D innovation, as a means to avoid the negative impact of stringent environmental regulations.     

地方官员特征、官员交流与环境治理——基于2003-2013年中国25个省级单位的经验证据

在治理环境的问题上,政府行为在很大程度会受到主政官员的影响.本文利用2003-2013年省级面板数据,分别从理论与实证两个方面考察了官员不同特征和地方官员交流对环境治理的影响.结果显示,在官员特征上,有过中央从政和在非特殊领域以及有过系统性管理工作经验的官员更有利于控制污染.除此之外,官员交流与环境污染治理也呈现了正相关关系.本文的发现是稳健的,有助于加深理解具有何种特征的官员与为何加强地方官员交流会有助于治理环境污染.
