注水过滤器滤芯主体质量可靠性试验与改进

结合采油现场实际，通过综合分析滤芯失效的表现形式，将滤芯材质、主体管壁厚度、过水孔密度作为影响滤芯主体现场使用寿命的三个可靠性主导影响因素，合理确定位极，科学设计试验方案；通过对过滤器滤芯主体的筛选试验，确定了经济合理、满足现场需要的滤芯主体。采用新型滤芯主体实现了在保持注水流量的同时，提高了滤芯的承压强度，可靠性增强。新型滤芯主体在正常工作压力环境中，使用时间平均为30天，是改进前的3倍。采用可拆洗式滤网结构,更换滤网方便快捷,减少了工人的劳动强度，可有效节约滤芯的成本投入,推广应用前景广阔。     

Benefits of Downward Earnings Management and Political Connection: Evidence from Government Subsidy and Market Pricing

This paper examines the role of downward earnings management and political connection on the receipt of government subsidies and market pricing of subsidies. Using subsidies data hand-collected from Chinese listed firms over the period 2004–2014, the results show a significantly positive association between downward earnings management and the receipt of government subsidies. The results also reveal that a firm's political connection is conducive to securing subsidies for poor performers, but not for good performers. Market pricing analyses demonstrate that share markets value subsidies positively in general, but the effect is ameliorated in firms conducting downward earnings management. No discernible difference is found between the market pricing of subsidies received by firms with political connections and those without.     

An international study of internal audit function quality

We investigate organisational and environmental factors that influence firms’ incentives to develop high-quality internal audit functions (IAFs) by using a unique international sample formed by matching proprietary data from a global internal auditor survey with public data obtained from Worldscope. Concerning organisational factors, we find that a positive relationship exists between IAF quality and firm complexity and confirm that complex firms have a higher demand for monitoring and advising and, therefore, a greater need for formal controls. In addition, IAF quality is positively related to board monitoring and audit committee diligence but negatively associated with CEO power, which suggests that IAF quality is influenced by other key players in corporate governance. Regarding environmental factors, we document that IAF quality is positively associated with industry competition, which implies that a firm’s incentive for a high-quality IAF is enhanced when confronted with greater environmental uncertainty. Furthermore, IAF quality has a significantly positive relationship with our self-constructed index of IAF requirements included in national corporate governance codes, which indicates that strong home-country corporate governance codes play a role in fostering IAF development.

The stained China miracle: Corruption,regulation, and firm performance

Regional corruptness in China has a positive effect on the profitability of private firms, but not that of state-owned firms. A natural experiment of exogenous trade policy change suggests that corruption may help private firms circumvent government regulation.     

制度创新与经济增长——一个理论分析框架及实证检验

任何经济增长过程都是在一定的制度环境中进行的，有必要将制度因素纳入经济增长理论当中。在新古典经济学框架下，本文通过理论模型分析，认为稳态下的经济增长率跟制度创新有着紧密的正向关的关系。在理论分析的基础上，本文基于1978～2012年的省际面板数据，利用半参数估计和线性回归估计方法，实证分析结果表明：国家财政干预的增强、国有经济的强化和垄断作用加强从整体上抑制了我国以及不同地区的经济增长，提高市场开放度和对产权的保护程度则对经济增长产生了积极的正向促进作用，制度差异是引起我国区域经济增长差异的重要因素之一，制度创新仍是当前我国经济增长的关键。     

菱角壳的化学成分和药理活性研究进展

近年来对菱角壳的研究主要分为化学成分和药理活性研究两个方面,其中化学成分方面的研究可以概括为生物碱、酚酸类、萜类和甾体、多糖类、黄酮类5个方面;药理活性方面的研究可以概括为抗癌活性、抗氧化活性、降低α-葡萄糖苷酶活性、保肝护肝活性、抗菌活性5个方面。目前在化学成分方面的研究较弱,从研究结果来看,没食子酸及其衍生物是菱角壳的主要药用成分。最后就菱角壳的开发利用提出了几点建议。
