重新考量国有商业银行改革——对引进境外战略投资者及上市的评析

国有商业银行引进境外战略投资者具有各种益处,但也同样会引发各种问题,诸如定价和境内战略投资者准入等等问题。目前而言,所存在问题亟待达成共识和得以妥善解决,从而实现双赢。国有商业银行作为真正的蓝筹股在境外上市,不能不说是中国股票市场的悲哀和无奈。就人才而论,中国投资银行完全具有作为中国工商银行的保荐人的能力,他们所缺乏的是风险意识。商业银行上市是否成功,不能凭空而论,只能在运营中去观察。政策选择不能为上市而上市,更不能为上市而引进战略投资者。     

外资入股中国银行业：如何超越“贱卖”的争论与分歧

2005年以来,外资入股中国银行业显著加速,国外银行机构进入中国银行业的路径也明显转换。国有银行股权“贱卖贵卖”之争实质上是监管制度和金融市场差异所致。我们认为,在中国银行业开放的过程中,不应当局限在银行贱卖贵卖之争,而应当在此基础上深入思考整个经济金融体系的改革问题。

The effectiveness of price-stabilizing share buybacks: Evidence from listed firms in Vietnam

The majority of share buybacks in Vietnam involve the sole stated purpose of price stabilization. Using a sample of repurchases announced in 2008–2016 and control firms based on propensity score matching, we find the Vietnamese repurchases to be effective in stabilizing prices and enhancing liquidity. Utilizing the special disclosure features in Vietnam that allow clearly-defined sub-windows of pre-trading, trading, and post-trading, we further examine the different mechanisms of market reactions and actual firm buyback transactions in the buyback process. We document significantly higher abnormal returns over the pre-trading window driven by market reactions, and improved liquidity and reduced volatility over the firm’s actual transaction window for the buyback firms. We also report a significant moderating effect of target shares announced and actual shares repurchased depending on the sub-window under examination. We do not find any evidence of effectiveness in the post-trading window or over a longer-term beyond the buyback period.     

股权质押下的控股股东增持:“价值信号”还是“行为信号”？

在股权质押的背景下,理性的控股股东会利用投资者的有限理性,通过增持向市场发送行为信号来提振股价,以缓解控制权转移风险。研究发现:股权质押下控股股东更有可能增持;短期内增持公告产生了正向的市场反应,其程度在非质押组和质押组间无显著差异;而长期来看,增持后质押组的长期股价以及经营绩效表现弱于其对照组,而非质押组则好于其对照组,说明股权质押下的增持并不是价值信号,而是行为信号。进一步研究发现,质押对增持的正向效应在高平仓压力组、低公司质量组、监管环境较宽松的欠发达地区更显著。拓展性检验表明,在考虑减持影响后,股权质押下控股股东更倾向于通过二级市场买卖和竞价交易实施净增持,并且管理层与其他大股东也会在一定程度上迎合控股股东的增持行为。最后本文排除了传统增持动机假说对上述结论的替代性解释。     

Are imputation credits capitalised into stock prices?

We investigate whether imputation tax credits are capitalised into Australian stock prices by utilising discounted cash‐flow valuation models and examining the relation between earnings yields and imputation credit yields. While imputation credits are valuable to many investors, the evidence that they are reflected in share prices is at best mixed and largely unconvincing. Our results reveal that imputation credits fail to lower realised returns casting doubts over whether imputation credits are priced from the perspective of longer‐term buy‐and‐hold investors. If so, such investors can expect to fully benefit from their imputation credits, and imputation effects may not impact on the cost of capital.     

Split Share Structure Reform,corporate governance,and the foreign share discount puzzle in China

We examine the impact of the Split Share Structure Reform on the well-known foreign share discount puzzle in China. Existing literature confirms that foreign investors are more concerned about insider expropriation because of their information disadvantage relative to domestic investors. The split share structure of the ownership of Chinese listed firms created a conflict of interests between state and private shareholders. Since, before the reform, state shareholders held restricted shares that denied them any wealth effect from share price movements, they had a limited incentive to work with private shareholders to ensure that managers maximized the stock market value of the firm. By abolishing the trading restrictions for state shareholders, this reform has increased the incentive alignment between state and private shareholders, encouraging them to monitor managers. If foreign investors’ concerns over the corporate governance implications of the split share structure at least partly contributed to their discounting of Chinese listed firms, then this discount should be reduced following the reform. Indeed, our evidence confirms this prediction, especially among Chinese listed firms with more state ownership or restricted shares. Our findings imply that this significant institutional reform of the Chinese stock market has benefitted minority investors.

房地产价格与国民收入分配的互动关系——基于联立方程模型的实证研究

本文基于省级面板数据,运用联立方程模型(SEM)和两阶段最小二乘(TSLS)估计法研究发现,房价与国民收入分配中的资本收入份额存在相互作用关系。房价上涨1%会使资本收入份额提升0.16%到0.43%,资本收入份额上升1%则会推动房价上涨约0.39%到0.54%。不过,这种相互作用机制存在一定的区域异质性,即在东部地区资本收入份额的提高会显著推高房价,而中西部地区后者对前者的影响效应更为明显。要实现房地产市场的健康成长,离不开国民收入分配结构的调整优化,而鼓励对适合我国劳动力比较优势的实体经济进行投资、减少资本对房地产的投机炒作,将有助于促进国民收入分配中劳动收入份额的提升。     

我国航空运输业市场结构演变分析

在阐述市场结构分析的主要理论和方法的基础上,测算了我国主要航空公司近年来市场份额的比重和变化,分析了市场结构变化特点。根据产业经济学中市场结构的相关理论,利用行业集中度和赫芬达尔-赫希曼指数两个指标,结合我国航空运输业的实践,计算了我国航空运输业市场2001—2009年的绝对集中度、HHI指数和倒数N指数,一致得出我国航空运输业是一个寡头垄断型产业,其垄断强弱程度呈"增强—减弱—增强"动态变化。
