再融资监管促进企业理性投资了吗？——来自中国上市公司的证据

本文以2007-2016年的A股上市公司为样本,实证检验中国再融资监管制度是否促进了企业的理性投资行为。研究发现:上市企业投资决策符合资本成本约束的理性准则,表明中国权益市场中存在普遍的市场约束力量;但企业再融资后投资理性程度明显降低;对监管失效的原因分析表明,企业投资理性程度下降受到事前融资动机和事后募资投向变更的影响:监管规则对事前再融资动机缺乏有效把控,导致再融资资格出现错配;而对事后募资用途的监管不严,则导致部分企业对募集资金的用途进行随意变更,使得企业投资理性程度降低。研究结论为完善企业投资决策自治机制、优化权益再融资监管、促进资本市场改革提供了实证依据和一定的现实启示。     

实现技术进步型经济增长的条件、路径和策略研究——基于人力资本投资的视角

提高创新效率和人力资本投资效率,采取渐进式技术进步以及经济危机的爆发和环保要求的提高等等,都可以激励企业家创新和劳动者的人力资本投资,使人力资本与技术进步形成一个良性循环,这决定了技术进步型经济增长的实现。随着创新和人力资本投资的不断进行,生产模式将不断更新,那么前后相继新旧生产模式的生产曲线的包络线就构成了经济增长的路径。发展中国家依靠技术模仿,可以发挥"后发优势"而实现短期高速增长,但是这种增长模式很难持续。采用技术模仿与技术创新相结合的技术进步方式,才是发展中国家实现长期增长和经济赶超的最佳策略。

上证A股与B股市场的羊群效应比较研究

为研究国内股票市场中投资者的羊群行为,选取2006年1月4日到2010年11月19日上证A、B股的日收益率数据,采用羊群效应测度的CCK模型,分别用最小二乘法和分位数回归法对股票市场的羊群效应进行实证分析。研究显示,上证B股市场的羊群效应始终强于A股,上证A、B股市场中上涨市和下跌市中的羊群效应是不同的,上涨下跌市中的羊群效应强弱随着分位数的不同而改变。     

山东省农村居民消费结构实证分析

Migrate for education: An unintended effect of school district combination in rural China

A large number of village primary schools in rural China were closed since the 1990s. This paper studies the impact of the reduction in the number of primary schools on the migration decision of rural residents. First, using China Health and Nutrition Survey that contains information on community characteristics, we find that both the disappearance of village primary school and the increased distance to nearby primary school increased the migration probability of village residents. Second, using the 1% population survey in 2005 and prefecture level information, we find that the decline in the number of primary schools between 2000 and 2004 increased the migration probability of rural residents. Exploring the heterogeneous effects, we find that the migration of individuals with primary-school-age children is more sensitive to the relocation of primary schools, and that the effect is stronger for families with boys than those with girls. These results suggest that human capital investment motive and regional education policy play an important role in China's urbanization process.     

论公共产品理论与劳动价值论的耦合及其意义

传统劳动价值论对商品范围的界定存在局限。如果把所有能够满足人们需要的用来交换的劳动成果,不管是有形的还是无形的都视为商品,商品就包括私人商品和公共商品(产品)两大类,基于这一认识,实现公共商品(产品)理论与劳动价值论的耦合,不仅有助于丰富、完善劳动价值论,使之经济解释力增强,而且有助于丰富、完善公共产品理论,使之真正成为财政学的理论基础。     

A new approach for the input–output price model

This paper proposes a new approach to measure the impact of a sector's price shock on price indices. It works based on table adjustments to trace the effects of any initial price shock through an iteration process. It has the same accuracy and all the capabilities of the popular Standard Leontief Price (SLP) model. A distinct advantage of the new approach compared with the SLP model, however, is its ability to measure the impact of the initial price shock on all value-added components if and when it is required. This capability enables researchers to use interindustry price analysis to tackle problems of a more real-world nature. Other advantages of this approach are its simple computational implementation, especially relevant for larger size interindustry tables, the unified way to deal with all kind of different price issues, and the yielding of an adjusted interindustry table reflecting all endogenous price adjustments in response to the initial price shock.     

人民币汇率变动对我国服务贸易竞争力影响的实证分析

利用贸易竞争力指数模型测算了1982-2010年我国服务贸易竞争力水平;运用Granger因果关系检验、协整检验与脉冲响应函数,实证分析人民币汇率变动对我国服务贸易竞争力影响。得到的结论是:人民币汇率变化是引起我国服务贸易竞争力变化的原因;无论是长期,还是短期,人民币汇率升值对我国服务贸易竞争力均有不利影响。     

Tariffs versus anti-dumping duties

Tariffs and anti-dumping duties are two important tools used to protect industries from foreign competition and to generate revenue. While the two tools have been studied extensively in separate contexts, little is known about their comparative effects. This paper compares their effects on prices, profits, government revenue, industry protection, and welfare in a two-country framework where a dominant firm in one country exports to the other inhabited by an oligopoly. Conditions under which one tool dominates the other for a given criterion are provided.
