对我国排污权交易会计问题探析

我国自20世纪80年代引入排污权交易后,呈现出国家日益重视、中央和地方积极推动、试点工作由点到面逐渐展开等特点。然而,从实际情况看,排污权交易市场的发展并不如理论预期的那样良好。出现此种状况的原因是多方面的,可以肯定的是,相关会计问题混乱不清或没能得到妥善解决是制约排污权交易市场发展的主要因素之一。本文将对排污权交易活动所面临的主要会计问题进行归纳,并提出对这些问题的思考和见解。

浅谈可交易排污权

排污是国家发展和城市建设无法回避的问题。如何在发展生产与环境保护之间寻求一种动态平衡值得我们思考。本文以可交易排污权为切点,探索我国经济与环境协调发展新途径。     

关于我国排污权交易会计处理的思考

可持续发展和节能减排呼唤排污权交易制度。实践证明,排污权交易是一种有效改善环境、降低污染治理费用的途径,为世界各国所欢迎和普遍采用。排污权交易的会计处理也成为理论界和实务界关注的焦点,目前来说,各国对排污权的确认、计量和披露都有不尽相同的规定。我国排污权交易实行时间还不长,还没有对其会计处理作出一个详尽的规定。本文拟在借鉴他国经验的基础上,对我国排污权交易的会计处理问题做一个粗浅探讨。

随着社会经济的发展,我国的排污管理体制已经不能适应环境保护的要求。排污权交易制度作为污染防治的经济手段,以其在降低治污成本、调动治污积极性方面不可替代的优势,越来越受到重视。本文对排污权交易制度的优越性及其发挥途径加以论述,并就排污权交易制度在我国的完善提出了建议。     

夜盘交易与中国铁矿石期货国际定价能力探讨

夜盘交易是试图提高中国铁矿石期货国际定价能力的重要举措。基于溢出指数模型,本文计算了中国铁矿石期货的国际定价能力,并采用回归模型实证研究了夜盘交易的实施和交易时间调整对中国铁矿石期货国际定价能力的影响。研究发现:第一,夜盘交易显著降低了中国铁矿石期货的国际定价能力;第二,缩短夜盘交易时间进一步恶化了中国铁矿石期货的国际定价能力;第三,引入境外投资者、控制期货市场的投机程度和波动率、及促进期货市场成交量增加均有利于提高中国铁矿石期货的国际定价能力。     

Option Trading and the Intervalling Effect Bias in Beta

Prior studies show that the beta coefficient of a security changes systematically as the length of measurement interval is varied. This phenomenon, which is called the intervalling effect bias in beta, has been attributed to the friction in the trading system that causes the delays in the price-adjustment process. This study shows that option listing is associated with a decline in the beta intervalling effect bias. The decline is most pronounced for small firms. We also find that our sample firms grow significantly after option listing. Since prior research indicates that market value is a major determinant of the magnitude of the intervalling effect, we re-examine our results using a subsample that controls for market value. The results indicate that the decline in the beta bias from the pre-listing to post-listing period is still prevalent after we control for the change in firm size. Overall, the evidence is consistent with the notion that option trading reduces the delays in the price-adjustment process, which in turn reduces the intervalling effect bias in beta.     

Insider Trading in the Hong Kong Stock Market

Many previous studies on insider trading are based ondata in the U.S. capital market and conclude thatinsiders can earn abnormal profits. This paperexamines abnormal price performance associated withinsider trading in the Hong Kong stock market. We findthat abnormal profits associated with insider tradingare all concentrated on small firms. Trading volumedoes matter in determining the magnitude of thoseabnormal profits. Our results show that insiders ofmedium-sized and large firms do not earn abnormalprofits. Finally, it is found that outsiders who mimicthe information of insider trades associated withmedium-sized and large firms cannot earn abnormalprofits.     

中国上市公司融资选择的市场时机效应——基于股票换手率和股票收益的实证检验

自从市场时机资本结构理论提出以来，国内外学者从理论的解释能力和实用性等方面对这一新兴融资决策理论进行了大量研究，并得出许多有意义的结论。然而目前的实证检验主要基于市值账面比（M／B）指标作为市场时机代理变量，这一指标引起学者们很大争议，研究结论缺乏可靠性。本文根据我国资本市场实际特征选择股票换手率作为市场时机代理变量，实证检验了市场时机与外部融资方式选择的关系，同时引入股票收益变量检验市场时机对资本结构动态变动的综合影响。研究结论显示，换手率在企业权益融资中具有重要作用，换手率较高时企业选择发行更多的股权融资，股票换手率和股票收益均对资本结构变动具有显著的负向影响。这表明我国上市公司确实存在着融资选择的市场时机效应。

Empirical Evidence on the Role of Trading Suspensions in Disseminating New Information to the Capital Market

Abstract:  This paper examines the effect of temporarily suspending the trading of exchange-listed individual stocks. We evaluate whether regulatory authorities can successfully use the mechanism of trading suspension in forcing companies to disclose new and material information to the capital market. Previous studies on trading suspensions mainly concentrate on North-American stock markets and find conflicting results. This study utilizes a new data set comprising of firms listed on Euronext Brussels – an important segment of Europe's leading cross-border exchange. Our results show that suspension is indeed an effective means of disseminating new information. Stock prices adjust completely and instantaneously to the new information released during trading suspensions. We also observe a significant increase in trading volume with the reinstatement of trading. On the other hand, we do not find support for the claim that trading suspensions increase the volatility of stock prices. Overall, our results show the efficacy of trading suspensions in disseminating new information.     

股票期权的个人所得税问题探讨

股票期权制度是一种新型的薪酬激励制度。股票期权制度作为富有成效的激励制度之一，在发达国家得到了广泛的应用，已成为市场经济国家和地区的企业对员工进行长期激励的非常普遍的方式。近两年来，股票期权成为我国企业改革和发展的一个热门话题，并在部分企业开始实施。如何针对股票期权所得的特点，并借鉴国外经验，制定相应的税收政策，是我们迫切需要解决的问题。本对我国股票期权所得税目、纳税义务发生时间、计税依据、税收优惠及税收征管等作了较为详细的探讨。     

Option trading after the opening bell and intraday stock return predictability

Prior literature finds that information is reflected in option markets before stock markets, but no study has explored whether option volume soon after market open has predictive power for intraday stock returns. Using novel intraday signed option-to-stock volume data, we find that a composite option trading score (OTS) in the first 30 min of market open predicts stock returns during the rest of the trading day. Such return predictability is greater for smaller stocks, stocks with higher idiosyncratic volatility, and stocks with higher bid–ask spreads relative to their options’ bid–ask spreads. Moreover, OTS is a significantly stronger predictor of intraday stock returns after overnight earnings announcements. The evidence suggests that option trading in the 30 min after the opening bell has predictive power for intraday stock returns.     

Technical Trading Rules in Emerging Markets and the 1997 Asian Currency Crises

The ability of simple technical trading rules to forecast future stock market movements is considered for seventeen emerging markets, sampled from January 1986 to September 2003. Some of the trading rules considered generated significant returns; this information could be exploited profitably on occasion. Market conditions and trading volume are found to be important to determining the usefulness of technical trading rules.     

Feed-In Tariff for Onshore Wind Power in China

This article estimated the cost of onshore wind power in China by employing levelized cost of the electricity model. The analytical framework has enough precision for appraising the effectiveness of feed-in tariff (FIT) policy. Results show that the existing FIT policy is attractive to investors, but serious curtailment and turbine quality issues could make wind power unprofitable. Meanwhile, rapid learning-by-doing in turbine price has substantially lowered the cost of wind power and made it competitive with coal power in 2013. Our estimate results indicate that it is necessary and the right time to reform the FIT policy for the newly commissioned wind farms.
