我国开放式基金业绩持续性的实证检验

本文运用绩效二分法和横截面回归方法对我国开放式基金的业绩持续性进行了检验。实证结果发现,我国开放式基金从总体上看业绩持续性不强,业绩持续性只是在短期内出现,基金经理不能连续战胜市场。此外,开放式基金在短期内还有显著的业绩反转现象产生,说明很难根据基金过去的收益来判断其未来的业绩。

政府研发补助对东北高端装备制造企业创新绩效的影响

以2012-2016年东北高端装备制造上市公司面板数据为样本,实证分析了政府研发补助对企业创新绩效的作用关系,同时分析该作用路径下企业研发投入的中介作用以及高管人力资本的调节作用。研究发现：政府研发补助对企业研发投入与创新绩效均有显著正向作用,企业研发投入在政府研发补助与企业创新绩效关系中起完全中介作用;高管任期负向调节政府研发补助与企业研发投入的关系,但正向调节企业研发投入与创新绩效的关系;高管学历在政府研发补助-企业研发投入-企业创新绩效的作用路径中,均起显著正向调节作用。     

中国全过程减排效应实证研究——以省域二氧化硫减排为例

全过程污染减排,是以经济发展模式转变为前提,构建从资源能源消费,污染物产生以及到污染排放的全过程减排机制.文章以省城二氧化硫减排为例,根据全过程减排内涵,选择减排率作为全过程减排评价指标,选择节能降耗、技术进步、产业结构、治污、监管激励等环节指标,对中国全过程减排效应进行实证分析.结果表明,全过程污染减排已在中国存在一定程度的效应.作为“中端”减排的三产比重效应较小,而技术进步效应更小,这应该是今后减排工作的重点.由此提出相应的政策建议.

Alternative futures and foreign direct investment in China

Chinese history is littered with sharp policy swings, and the communist era, which has not yet fully drawn to a close, has witnessed a veritable embarrassment of riches. This has provided a fertile ground for researchers engaged in crystal ball gazing. Recently, momentum has accelerated on that front, a development apparently reflecting the increasingly fluid political‐economic conditions in the country. The scenarios generated can serve as an effective reference point in planning exercises, but there is scope for solidifying the conceptual architecture. The issue of rendering them highly relevant to foreign investors, presumably very important potential consumers of the product, should also be addressed.     

Regulatory effects on the market penetration and capacity of reliability differentiated service

This paper investigates the effects of alternative forms of regulation on the market penetration and capacity that are determined by a profit-maximizing monopolist providing reliability differentiated service to consumers. Both price cap and rate of return regulation lead to larger capacity and market penetration than in the absence of regulation. These forms of regulation also lead to larger consumer surplus than in the absence of regulation. A minimum reliability standard reduces market penetration, and this reduction may lead to a decrease in consumer surplus.      

The Reaction of Closed End Funds to Stock Distribution Announcements

This study examines the impact of stock split and stock dividend announcements made by closed end mutual funds. We argue that the asymmetric information / signaling hypothesis does not apply to mutual funds. Therefore, any announcement effects must be attributed to other factors such as the optimal trading range hypothesis. We find that closed end funds react no differently than other firms to stock distribution announcements; also, trading volume and turnover remain unchanged after closed end funds' ex-stock distribution days, while liquidity declines for other firms that distribute shares.     

Advertisement policy for dual-channel within emissions-controlled flexible production system

Nowadays, industrial firms are very much careful to build a green environment by reducing carbon emissions. The government imposes some rules and regulations to provide a better eco-friendly environment. In this study, the cap-and-trade mechanism has been considered in a production model to control the carbon emissions rate. The manufacturers invest in advanced green technology to reduce per unit emissions. As online and offline selling is crucial to any industry for increasing customer demand, the manufacturers sell their products by dual-channel and advertise their products by online channel to make more popular of their products. Keeping these in mind, a sustainable flexible production model with single-type substitutable product production is considered here by imposing a cap-and-tax policy, investing in green technology, and advertising for products. This model is divided into two cases: with and without investment in green technology. The demand of each manufacturer depends upon an online selling price, an offline selling price, and an online advertisement of the product. A classical optimization technique helps to get the optimum strategies for the online selling price, offline selling price, advertisement investment, green technology, cycle time, and production rate. From the numerical study, it is proved that the industry gets 6.97% more profit in the case of green technology investment and the proposed study gives 5.74% more profit than the traditional production system. Sensitivity analysis and managerial insights are performed.
