国有产权、公司特征与困境公司绩效

尽管众多研究表明国有产权在公司正常经营期间会降低绩效,但一旦陷入财务困境,源于国有产权的预算软约束却可以降低财务困境成本,从而有利于国有公司。本文以1999—2005年期间发生财务困境的上市公司为研究对象,发现在财务困境期间国有产权对公司绩效具有积极影响,并且当公司规模较小或者财务杠杆较高时,这种积极作用更为明显。     

基于制度变迁理论谈会计准则全球化

会计准则全球化从总体上讲是一种降低交易费用的制度安排。在经济全球化进程中,国际贸易迅速发展,资本全球流动,而会计作为一种通用的国际商用语言,会计准则全球化是必然趋势。本文试用制度变迁理论分析会计准则全球化以及我国如何面对会计准则全球化的未来。     

Accounting-based regulation in emerging markets: The case of China's seasoned-equity offerings

In China, listed companies are required to achieve a minimum return on equity (ROE) before they can apply for permission to issue additional shares through seasoned-equity offerings (SEO). We document two benefits of this accounting-based regulation in China. First, this regulation limits the increase in the supply of shares and the dilution of existing share prices. The Chinese stock market reacted positively to the announcement of this accounting-based regulation. Moreover, investors' reactions to SEO, announcements are less negative since the accounting-based regulation was introduced than before the regulation was enacted. The second benefit is that the regulation reduces adverse selection in SEO, as shown by the finding that prior to this regulation, firms below the ROE threshold underperformed the market after their SEO, much like what has been observed in other markets; while those above the threshold outperformed the market. Thus, although positive accounting theory predicts that regulations based on accounting numbers create incentives for managers to manipulate their accounting numbers, accounting-based regulations in China seem to serve some useful purposes.

UHMWPE对UHMWPE/UHMWPP共混冻胶纤维性能的影响

研究了超高分子质量聚乙烯（UHMWPE）对超高分子质量聚丙烯（UHMWPP）／UHMWPE共混冻胶纤维结晶性能、热学性能、形态结构以及力学性能的影响。结果表明：随着UHMWPE含量的增加，共混纤维结构具有更好的连贯性，并显示出较好的热学性能；当UHMWPE含量超过一定比例时，虽然共混纤维的热学性能下降，但在共混纤维中呈现出明显的类似“钢筋混凝土”结构，从而大大地提高了共混纤维的力学性能。     

Contingency view on technological differentiation and firm performance: evidence in an economic downturn

Although the importance of strategy for firm performance has been studied, little evidence has been offered regarding this linkage in hostile environments characterized by a lack of exploitable market opportunity and fiercer competition. This study aims to examine the viability of strategic postures of technological differentiation in such a setting using data from 1,054 samples across 32 industries in 30 countries during 2001–2002, when global economies suffered a downturn. The empirical results show that differentiation-oriented firms underperformed efficiency-oriented ones during this period. However, in the face of deteriorating market conditions, a strategic orientation toward technological differentiation, in concert with an internal commitment to R&D investment or external munificence toward technological opportunity, yields better performance. Finally, this study finds that firms with tight coupling between differentiation and efficiency outmaneuver those with a pure strategy or no strategy at the time of an economic downturn.     

我国县域经济可持续发展问题与对策探析

县域经济已经成为我国国民经济的重要组成部分。目前我国县域经济存在发展不平衡、产业层次和劳动力素质低下、自然资源浪费、生态环境恶化、产业要素缺乏、国家投入不合理等问题。我们应该制定县域经济的发展规划,加强对县域经济的分类指导;积极推进农业产业化,切实提高农民收入;提高劳动力素质;节约使用自然资源,保护生态环境;积极推进城镇化,促进城乡协调发展。     

人力资源管理实践对企业绩效影响的框架模型研究

人力资源是企业重要的战略性资源,是企业发展最为关键的要素,这是企业界普遍认同的一个观点,但是如何采取适当的人力资源管理实践是企业进行管理的一个难题。针对这一问题,本文主要探讨人力资源管理实践是如何影响制约着企业的绩效,何种人力资源管理实践系统有助于企业绩效的提高,也就是本文所提出的承诺型人力资源管理实践系统是如何协同发挥作用的。
