通过加总推出的总供给曲线

总供给曲线的推导是宏观经济学中的最重要内容之一。在大多数宏观经济模型中 ,在推导总供给曲线时 ,加总问题 (aggregationproblem)往往被忽略。一般认为 ,总供给曲线是各企业供给曲线的简单算术和或是一个代表性企业供给曲线的简单放大。但是 ,在现实中 ,各个企业是不同的。只有在非常严格的条件下 ,总供给曲线与企业供给曲线在性质上才是等价的。考虑到中国经济的制度性特点并在解决加总的一系列技术问题的基础上 ,本文推导出了在企业劳动生产率服从均匀分布情况下的总供给曲线。通过这种方法推出的总供给曲线具有许多传统总供给曲线所不具有的新性质。笔者希望本文能为进一步研究处于微观经济和宏观经济之间的往往被忽视的一块重要领域 (“中观经济领域”)做出贡献。

Industrial development in the inland region of China: A case study of the motorcycle industry

Although the inland region of China has generally been left behind in economic development compared with the coastal region, the motorcycle industry in Chongqing has recorded remarkable growth due to the meteoric rise of private enterprises over the last decade. Based on panel data of enterprises, we attempt to identify the factors behind the dynamic development of this industry. We conclude that the success of the motorcycle industry in Chongqing is attributable to a combination of positive features from the Wenzhou model in the 1990s, in which industrial development is based on clustering of private enterprises, and the Sunan model in the 1980s, in which industrial development is based on the effective use of human resources recruited from existing state-owned enterprises (SOEs). Learning by collective enterprises from SOEs in Chongqing coupled with the growth of the private enterprise sector fostered cluster-based industrial development.

人民币升值及我国的应对措施

人民币升值已经是我国无法回避的问题。总体来看,在现阶段对于我国宏观经济均衡目标而言,人民币升值比不升值对我国经济更有利。但人民币升值的速度取决于我国企业对人民币升值的承受能力、我国扩大内需的能力、我国政府掌控人民币汇率的能力以及热钱流入的速度和资产价格泡沫的大小等。其中,扩大内需是最根本的决定因素。本文提出了在短期内扩大内需以应对人民币升值的两个主要措施,即放松计划生育政策和进行大规模生态开发。

Weekday seasonality of stock returns: The contrary case of China

We document that Chinese stock returns exhibit early-in-the-week effects opposite-signed to those observed worldwide. The period of analysis is 2001–2016. Dominated by individual investors, Chinese stock markets offer unique out-of-sample insight regarding the source of weekday seasonality, ascribed elsewhere to institutional investors’ trading patterns. High returns to the market and to small, speculative stocks early-in-the-week pose a refuter to the mood explanation for the conventional (negative) Monday effect. A battery of tests suggests that the patterns in the Market, SMB, and RMW factors are jointly associated with Chinese individual investors whose demand is tilted towards small, speculative stocks. Our findings point to a potential role of dominant investor type in driving weekday patterns and the RMW premium.     

Separation of ownership and control for Chinese listed firms: Effect on the cost of debt and the moderating role of bank competition

This research investigates the effect of the separation between firm ownership and control on the cost of debt, with attention to the moderating role of state ownership and bank competition. We make use of a sample of 1744 Chinese A-share firms for the years 2011–2017. We find that separation between ownership and control is positively associated with the cost of debt. This is consistent with the view that separation of control from ownership allows controlling shareholders to engage in tunneling and other behaviors that increase the risk of default. State ownership weakens this positive link because government debt guarantees mitigate the risk of default. Greater competition in the banking industry generally reduces the cost of debt for non-state enterprises while having no effect for state enterprises. At the same time, greater bank competition amplifies the positive effect of ownership and control separation on debt cost for non-state enterprises as banks must still cover the higher default risk. Finally, the global financial crisis raised the cost of debt for non-state enterprises but had no effect for state enterprises.     

基于专利强度分析的区域中药材产业创新水平评价

中药材产业创新能力是中医药事业高质量传承发展的保障。以2009-2018年中国中药材产业已授权发明专利为研究对象。首先构建10个可量化的专利强度评价指标,用CRITIC赋权法对专利指标进行赋权,计算单个专利的专利强度。然后用正态分布函数划分专利强度等级,计算全国各省份的专利强度等级占比。最后以专利强度等级占比情况凸显产业创新发展水平,发现沿海以及围绕直辖市的省份的中药材产业创新发展水平良好,西部欠发达地区创新水平还有很大的发展空间,说明中药材产业创新发展能力与资源分配和经济发展有很大的关系。
