浅析新形势下财务管理对石油化工产业的作用

石油化工产业相较于其他的行业具有较大的发展规模,并且具有很强的经济实力。在开展日常管理工作中,相关事务较为繁杂,尤其是企业管理层具有较为复杂的结构,经营的主要业务为国家原油及与化工有关的产品,因此,其经营活动有着较高的风险。在这样的情况下,石油化工企业为了自身的可持续发展,应该确保财务管理工作与自身发展趋势相符合。     

年轻高管与企业股价崩盘风险：来自“代理冲突观”的证据*

在企业纷纷实施高管年轻化战略的背景下，本文从股价崩盘风险的视角分析和检验了年轻高管风险偏好的经济后果及其作用机理。本文基于“个体认知观”和“代理冲突观”展开理论推演，采用中国沪深A股非金融上市公司的数据，检验发现，年轻高管会显著加剧企业未来的股价崩盘风险，且这种影响主要存在于民营企业，在国有企业并不显著。进一步针对具体作用机制的检验发现，年轻高管在投资决策中选择了更多能迅速提升个人收益的风险性投资项目，但在不能迅速提升个人收益的风险性投资项目上与年长高管没有显著差异。同时，年轻高管对股价崩盘风险的加剧效应仅仅存在于高管在上市公司领取薪酬的样本企业，且更高的独立董事比例能显著抑制年轻高管的股价崩盘风险加剧效应。这表明，年轻高管个体认知层面的风险偏好被其追求个人私利最大化的代理冲突所扭曲，进而为年轻高管风险偏好的“代理冲突观”提供了实证证据。     

社会化视域下企业自愿性人才流失现状及对策建议——以高校毕业新员工为例

社会化使新员工明晰了任务角色,帮助新员工完成职业进化,从根源上审视人和企业的不匹配问题,为高层次新员工流失困境的突破提供了崭新的视角。文章在阐述我国高校毕业新员工自愿性人才流失概况,挖掘其离职深层原因的前提下,探究组织社会化对人才流失的预防和规避作用,并分别从新员工自身和企业环境这两个角度提出相应对策。     

焦化厂深化厂务公开工作情况的调研报告

厂务公开是企业民主管理工作的重要组成部分。近年来,焦化厂通过推行厂务公开民主管理工作,实现了从厂部到车间及至班组的三级网络公开体系,形成了常规性工作定期公开,长期性、阶段性工作分阶段公开,短期、临时性工作随时公开的良好态势。使职工的知情权、参与权和监督得到有效的落实,为现代企业发展提供了强有力的支撑。     

异质性媒体与资本市场信息效率

新闻传媒通过其信息处理和传播功能 ,对资本市场的信息整合产生了重要影响.不同于以往的研究 ,文章深入新闻传媒行业内部 ,探讨了不同类别的媒体(中央媒体与各地方媒体)对中国资本市场信息效率的差异化影响.研究发现:中央媒体既可以直接提升资本市场信息效率 ,又可以通过削弱政治关联对资本市场信息整合的不利影响,间接改善资本市场信息效率;地方媒体虽然能够直接提升资本市场信息效率 ,但是无力削弱政治关联对资本市场信息整合的不利影响 ,其间接渠道并不起作用.这一结果考虑了媒体跟踪上市公司时可能产生的内生性问题 ,在一系列稳健性测试中始终存在.文章认为 ,相对于地方媒体 ,中央媒体在信息透明度较低情况下的信息获取和处理的能力优势 ,以及面对政治关联时保持客观报道的独立性优势,可以解释这一发现.

Corruption,Financial Resources and Exports

This paper argues that a country's comparative advantage in exports depends on both the factor abundance and the allocation efficiency of the endowments. However, the latter is not considered in the traditional Heckscher–Ohlin model. In line with the “sand” view of corruption, this paper empirically studies the role of corruption in shaping a country's export pattern by distorting the allocation of financial resources. We find that the resource misallocation resulting from corruption undermines the export growth promoted by the positive external financial shock. The negative effects are realized by the extensive margins instead of the intensive margins of heterogeneous firms.     

Updating Input–Output Tables with Benchmark Table Series

Numerous methods have been proposed to update input–output (I–O) tables. They rely on the assumption that the economic structure will not change significantly during the interpolation period. However, this assumption may not always hold, particularly for countries experiencing rapid development. This study attempts to combine forecasting with a matrix transformation technique (MTT) to provide a new perspective on updating I–O tables. Under the assumption that changes in the trend of an economic structure are statistically significant, the method extrapolates I–O tables by combining time series models with an MTT and proceeds with only the total value added during the target years. A simulation study and empirical analysis are conducted to compare the forecasting performance of the MTT to the Generalized RAS (GRAS) and Kuroda methods. The results show that the comprehensive performance of the MTT is better than the performance of the GRAS and Kuroda methods, as measured by the Standardized Total Percentage Error, Theil's U and Mean Absolute Percentage Error indices.     

Financial analyst coverage for U.S. firms facing foreign competition: Evidence from trade liberalization

This study examines financial analyst coverage for U.S. firms following an increase in foreign product market competition. To capture exogenous shocks to domestic firms' competitive environments, we exploit a quasi‐natural experiment from large import tariff reductions over the 1984 to 2005 period in the manufacturing sector. Using data for the years before and after large tariff reductions, our difference‐in‐differences analysis shows evidence of a significant decrease in analyst coverage for incumbent U.S. firms when they face greater entry threat from foreign competitors. We also find that analysts with less firm‐specific experience and less accurate prior‐period forecasts are more likely to stop following the domestic firm when foreign competition intensifies. Overall, the findings suggest that foreign product market competition from global trade liberalization is an important determinant of financial analysts' coverage decisions.     

制造业投入数字化与全球价值链中高端跃升——基于投入来源差异的再检验

数字化浪潮驱动着全球价值链重构,为中国制造业企业提供了后发赶超的绝佳契机;然而,在跨国公司阻截、"逆全球化"思潮与突发公共事件导致全球价值链断裂与科技脱钩风险加剧的背景下,无视数字投入的来源差异而笼统地关注数字化的贸易所得效应难免出现结论偏误.文章基于WIOD投入产出数据库、中国工业企业数据库和海关进出口数据库,识别数字投入的国家属性,检验了依赖不同来源的投入数字化对企业全球价值链分工地位(以出口国内附加值率EDVAR表征)的微观效应.研究发现:(1)国内来源的数字投入对企业EDVAR具有显著的提升作用,而国外来源的数字投入对企业EDVAR具有显著的抑制作用.(2)投入数字化通过成本加成与创新渠道作用于企业EDVAR,且依赖不同来源的投入数字化在各渠道下表现迥异.(3)数字贸易壁垒进一步加剧了国外数字投入对企业EDVAR的抑制作用.文章研究结论为我国制造业走出"自主可控"的数字化之路和实现高附加值创造的"弯道超越"提供了经验证据与政策依据.
