我国上市公司社会责任会计信息市场反应实证分析

本文抽样分析了我国上市公司社会责任会计信息披露的现状,同时通过建立上市公司对利益相关者承担的社会责任贡献的指标体系,揭示了我国深市、沪市所有上市公司的真实社会贡献,并实证分析了市场对这一信息的反应。实证结果表明:现阶段这一信息与我国上市公司价值的相关性不强,但是,由于行业特色的存在,不同行业之间的价值相关性迥异。这一实证结果给我国社会责任会计的发展带来了一些有意义的启示。     

正确认识与开展税务服务

本期刊发了东北财经大学马国强教授《正确认识与开展税务服务》一文。文章认为:税收管理的目的是为了促使纳税人依法纳税,其内容包括税收服务、税收监控、税收保卫和税收救济。税务服务是税务机关为了为满足纳税人需要,促使纳税人依法纳税而提供的税务方面的服务。税务服务包括税收宣传和税收咨询两大方面的内容,前者主要是实施税收教育,向纳税人灌输税收知识。后者主要是通过直接接触、信函、电话等联系方式,回答纳税人提出的问题;建立税收信息网站,供纳税人随时查阅税收信息。文章通过严谨的论述,澄清了一些模糊认识,颇具启发性。

中国不同省份金融结构转变与产业结构升级关系的实证研究

随着我国社会主义市场经济改革的不断深入，现有金融结构已不能适应经济发展。本文从金融结构调整的角度出发，对中国较发达地区，欠发达地区以及基于全国的数据进行面板回归。通过对实证结果的分析，得出金融结构调整对产业结构调整并不是简单线性关系的结论，金融结构调整应有合理的范围，当金融结构在其范围内变化时，能够促进经济的增长，当金融结构的调整超过合理范围时，金融功能的负作用会逐渐增强，当负作用积累到一定程度，会对经济的发展起到阻碍作用，我国各省份应根据自己的实际发展情况和自然禀赋，选择合适的金融结构和经济发展模式。     

Financial Imbalance Index as a New Early Warning Indicator： Methods and Applications in the Chinese Economy

Based on the stylized facts of financial crises and systemic risk accumulation, this paper constructs a new financial imbalance index （FII） from the perspective of endogenous financial cycles and assesses its application in China＇s macro-financial analysis. The results show that the FII is not only an effective index to detect financial imbalances in China＇s economic cycles, but is also more accurate than and plays more of a leading role than conventional indicators, such as the consumer price index, the financial conditions index and the purchasing managers indicator. Empirical analysis shows that the FII can be used as an effective indicator to measure systemic financial risk, and can provide policy-makers and market participants with useful information to make appropriate decisions.     

Convergence analysis and optimal strike choice for static hedges of general path-independent pay-offs

In this paper, we propose a new algorithm to find the optimal static replicating portfolios for general path-independent nonlinear pay-off functions and give an estimate for the rate of convergence that is absent in the literature. We choose the static replication by designing an adaptation function arising in the error bound between the nonlinear pay-off function and the linear spline approximation and derive the equidistribution equation for selecting the optimal strikes. The numerical tests for variance swaps, swaptions, static quadratic hedges and also for a jump-diffusion process, allowing for the default of the underlying asset, show that the proposed iterative equidistribution equation algorithm is simple, fast and accurate. The paper generalizes and improves the results on static replication and approximation in the literature.

The 52-week high momentum strategy in international stock markets

We study the 52-week high momentum strategy in international stock markets proposed by George and Hwang [George, T., Hwang, C.Y., 2004. The 52-week high and momentum investing. Journal of Finance 59, 2145-2176.]. This strategy produces profits in 18 of the 20 markets studied, and the profits are significant in 10 markets. The 52-week high momentum profits exist independently from the Jegadeesh and Titman [Jegadeesh, N., Titman, S., 1993. Returns to buying winners and selling losers: implications for market efficiency. Journal of Finance 48, 65-91.] individual stock and Moskowitz and Grinblatt [Moskowitz, T.J., Grinblatt, M., 1999. Do industries explain momentum? Journal of Finance 54, 1249-1290] industry momentum strategies. These profits do not show reversals in the long run. We find that the 52-week high is a better predictor of future returns than macroeconomic risk factors or the acquisition price. The individualism index, a proxy to the level of overconfidence, has no explanatory power to the variations of the 52-week high momentum profits across different markets. However, the profits are no longer significant in most markets once transaction costs are taken into account.     

规划建设沿边经济带的政策思考

规划建设沿边经济带是巩固边疆的战略举措,有利于保障国土安全和边疆社会稳定,促进区域协调发展,增进民族团结,改善与邻国边疆局面的关系.目前,自然地理条件普遍较差,人口分布稀少,经济发展和基础设施建设滞后,城市发育不足,营商环境不佳是我国沿边经济带发展的主要制约因素.规划建设沿边经济带,应以地级行政区为基础单元,聚焦于培育新的经济增长极、完善区域性中心城市功能和改善营商环境,需要国家和地方政府的大力支持,推进体制机制创新,加强国内区域和国际区域次区域合作.
