基于双重属性的商业模式构念化与研究框架建议

商业模式是创业研究的新兴主题,既有研究文献增长迅猛,但研究结论高度零散、矛盾甚至冲突,不少学者认为缺乏概念明确性是导致商业模式研究喧嚣混沌状况的根源,但鲜有研究对此做出积极的理论探索。本文首先梳理并提炼商业模式概念的演变及其理论逻辑,发现既有研究的不足并提炼商业模式如何创造价值的架构属性,基于不同理论视角形成了不同的概念维度,特别是对于商业模式如何塑造竞争优势的价值属性研究不足。进一步地,本文构建了基于双重属性的商业模式构念化与分类模型,目的在于整合并澄清学术界对于商业模式概念的学理性认识,同时基于该模型重新审视商业模式研究框架并提出未来研究亟待关注的关键问题,以期对商业模式形成、调整及其效应机制的理论发展和实证检验起到推动作用,最后提出了国内学者开展商业模式研究的启示和建议。     

Examining technological competition between BMW and Hyundai in the Korean car market

The Korean car market has increased in size. BMW and Hyundai are the top-ranked imported and domestic vehicle brands in Korea, respectively. Thus, it is important to understand these companies and the Korean car market, because technology is most significant in the vehicle industry. In this paper, we compare BMW with Hyundai from the technological perspective. Our research is focused on an analysis of the technological competition between BMW and Hyundai based on their developed technologies. We use all BMW and Hyundai patents from worldwide patent databases to analyse the two companies’ technologies. In addition, we apply statistical methods and machine learning algorithms to the patent analysis. In our conclusion, we show the technological differences and competition between BMW and Hyundai, and find their relative strengths and weaknesses.     

房地产属性、收入差距与房价变动趋势

以往关于收入差距与房价之间关系的研究,较少兼顾房地产的消费与投资双重属性。文章基于双重属性的角度,首先从理论上阐述了收入差距与房价之间的动态关系。在经济发展水平较低的情况下,房地产的消费属性凸显,收入差距扩大会抑制房价上涨;随着经济的进一步发展,房地产单一属性不明显,收入差距变化对房价不存在显著影响;当经济发展水平较高时,房地产投资属性占优,收入差距扩大会促进房价上涨。进一步对理论结果进行实证研究发现,整体上我国收入差距与房价之间无显著相关关系,单一属性不明显;但就省际差异而言,在经济发展水平较高的省份,收入差距促进了房价上涨,而在经济发展水平较低的省份,收入差距则抑制了房价上涨。随着时间的变化,收入差距由抑制房价上涨转变为促进房价上涨。

全尺寸评价方法标准化 提升油套管质量水平

油套管产品在油气勘探开发及生产过程中发挥着重要的作用,油套管产品质量的好坏直接关系着油气田的生产成本及使用寿命。通过分析油套管产品的使用现状,论述了油套管全尺寸评价标准在控制、提升油套管质量方面的重要作用。在分析、研究国际标准、油田工况、失效案例、科研成果的基础上,实现油套管全尺寸评价方法标准化,填补了我国油套管质量控制领域全尺寸评价标准的空白。全尺寸评价方法标准在油气田及生产厂推广实施情况表明,应用全尺寸性能评价标准,能够实现对油套管质量的全面控制,提升油套管产品质量,对油气勘探开发事业的发展具有重要的经济及社会意义。     

Disclosure policy in Tullock contests with asymmetric stochastic entry

We examine how disclosure policy can be optimally designed to incentivize contestants when their participation is exogenously stochastic. In a generalized Tullock contest setting with two players who are asymmetric in both their values and entry probabilities, we fully characterize the necessary and sufficient conditions under which no disclosure dominates full disclosure. We find that the comparison depends solely on a balance effect exercised by entry probabilities on the expected total effort. The optimal disclosure policy must better balance the competition. These conditions continue to hold when the precision r of Tullock contests is endogenously chosen by the designer.     

Uncovering the Truth about Chinese Urban Unemployment Rates: 2005–2012

Using China Urban Household Survey data from 2005 to 2012, the present paper examines the changing pattern of China's urban unemployment rates. The paper shows that the annual urban unemployment rates during 2005–2012 averaged approximately 8.5 percent, as opposed to the official figure of approximately 4.1 percent, and despite the significant slowdown of GDP growth since 2008, the urban unemployment rates still exhibit a downward trend. This paper finds that continuous job creation in both the tertiary and the non‐state sectors helps explain the decreasing trend in unemployment rates. Meanwhile, the downward trend of the unemployment rates could also be explained by the fact that both the secondary industry and the state‐owned sector have destructed fewer jobs because of the execution of macroeconomic stimulus policies since 2008.     

Dynamics and performance of decentralized portfolios with size-induced fund flows

Interpreting the effects of scale on fund performance, portfolio dynamics and management fees     

The Cost of Multiple Large Shareholders

Previous research argues that large noncontrolling shareholders enhance firm value because they deter expropriation by the controlling shareholder. We propose that the conflicting incentives faced by large shareholders may induce a nonlinear relationship between the relative size of large shareholdings and firm value. Consistent with this prediction, we present evidence that there are costs to having a second (and third) largest shareholder, especially when the largest shareholdings are similar in size. Our results are robust to various relative size proxies, firm performance measures, model specifications, and potential endogeneity issues.     

环境不确定性、企业社会责任与审计收费

以每股社会贡献值为企业社会责任表现的代理变量,研究在环境不确定条件下企业社会责任与审计收费的关系。结果显示,企业的社会责任表现与审计收费显著正相关,原因是企业可能通过良好的社会责任表现以转移利益相关者视线从而掩饰其盈余管理等行为,而审计师将会针对性地实施更多的审计程序,并提高风险估价,因而导致审计收费提高。进一步研究发现,环境不确定性是上述两者关系的调节性影响因素,相对于环境不确定性较低的企业,环境不确定性较高企业的社会责任表现与审计收费的关系更为显著,这说明如果企业在面临较高的环境不确定性时仍然有着良好的社会责任表现,将存在更大的掩饰其盈余管理等行为的可能,从而导致审计师更大幅度地提高审计收费。
