Solvency Ⅱ与C-ROSS非寿险保险风险最低资本要求比较研究——基于中国60家财产保险公司的经验证据

本文以非寿险业务保险风险最低资本要求为考察对象,研究了欧盟Solvency Ⅱ与中国C-ROSS的差异,并利用中国保险市场60家财险公司的经验数据,对两者之间的差异进行了实证和模拟分析。研究结果表明,Solvency Ⅱ和C-ROSS对中国财险公司保险风险最低资本要求存在差异。对于拥有传统业务结构的财险公司,Solvency Ⅱ对保险风险最低资本要求更高,但是这种差距随着公司业务规模的缩小而减弱;对于以经营某些专业险种为主的财险公司,主营业务险种对两者差异具有决定性影响。本文的研究结论详细解释了Solvency Ⅱ与C-ROSS在非寿险保险风险最低资本计算上的异同,对C-ROSS下一步的修订工作提供了一定的支持与参考。     

A Dynamic Study on Ecological Disaster,Government Regulation,and Renewable Resources

This article develops a dynamic model to investigate renewable resource markets under different property rights. We find that different property rights regimes in renewable resource markets yield very different equilibria. Under private property rights, the valve point increases with the natural growth rate, productivity, number of firms, and marginal costs. Under common property rights, “the tragedy of the commons” inescapably occurs. This study suggests how to avoid ecological disaster by implementing a set of public policies.     

我国软件外包承接城市效率评价与驱动因素研究

就 业问题、环境污染以及从业人员研发能力下降已经成为制约软件外包承接城市发展的瓶颈问 题。文章运用DEA方法构建考虑非期望产出和非合意变量的软件外包承接效率评价模型，重 点比较不同模型下我国软件外包承接城市效率的差异，并引入Tobit回归分析软件外包承接 城市效率的驱动因素。研究发现：我国软件外包承接城市的投入产出组合在逐步优化，且东 部沿海城市的效率值明显优于中西部城市，其中大连市的效率值始终为1，处于生产的前沿 面。另外，人才竞争力对软件外包承接城市效率有显著的正向影响，信息技术基础设施竞争力与承接效率的关系呈显著负相关。     

To blow or not to blow the whistle: the effects of potential harm,social pressure and organisational commitment on whistleblowing intention and behaviour

This study uses a rational ethical decision‐making framework to examine the influence of moral intensity (potential harm and social pressure) on whistleblowing intention and behaviour using organisational commitment as a moderator. A scenario was developed, and an online questionnaire was used to conduct an empirical analysis on the responses of 533 participants. The mean age and years of work experience of the respondents were 31 and 8.2 years, respectively. The results show, first, that while moral intensity is correlated with whistleblowing intention, only the potential harm is positively correlated with such intention. Second, potential harm and social pressure differentially affect whistleblower choice of using an internal or external channel. Third, organisational commitment has a moderated mediation effect among moral intensity, whistleblowing intention and behaviour. Fourth, whistleblowers may be grouped into four conceptual types: indifferent, rebel, mature and spoil. Finally, theoretical and managerial implications of the findings are discussed.
