保险企业数字化战略转型路径研究

数字经济的深入推进正深刻地改变着保险企业的内外部环境,数字化战略转型成为保险企业发展必然选择。本文首先从外部环境推动和内部能力重塑拉动两方面剖析了保险企业数字化战略转型的动因,随后对保险企业数字化战略转型的内涵和特征进行阐释,在此基础上构建了保险企业数字化战略转型的“转型动因-转型过程-转型成效”的实现框架。建议保险企业从客户交互端、业务运营端以及支持保障端三大层面及九大维度着手进行变革转型,本文的研究试图对企业数字化战略转型的理论研究和管理实践有所启示。     

Impact of Auditor Report Changes on Financial Reporting Quality and Audit Costs: Evidence from the United Kingdom

While substantial revisions to auditor reporting requirements are being implemented internationally, the impact of these reforms on financial reporting quality is unknown. We exploit the United Kingdom's recent auditor reporting changes and find that the United Kingdom's new reporting regime is associated with an improvement in financial reporting quality as proxied by significant decreases in absolute abnormal accruals and the propensity to just meet or beat analyst forecasts, and a significant increase in earnings response coefficients. As for audit costs, we do not find a significant change in audit fees or audit delay surrounding the implementation of the new reporting regime. Taken together, the results of this study suggest that new auditor reporting requirements are associated with a significant improvement in financial reporting quality without detecting a significant increase in audit costs.

数字经济对区域经济高质量发展的影响研究

推动数字经济发展,是我国在当下推动经济转型,促进高质量发展的重要战略。本文基于2012~2019年省级面板数据,构建双向固定效应模型,运用基准回归、异质性检验和分位数回归的方法进行实证研究发现,数字经济助推经济高质量发展的同时还存在地区差异,对西部影响最大,中部影响最小,而数字经济的发展水平又受到产业结构、技术创新等因素影响。因此,本文针对不同地区差异分别提出建议,从而促进持续更新发展理念,以创新驱动发展,优化产业结构为数字经济提供良好环境,以期推动数字经济建设发展。     

Minimal Hellinger martingale measures of order <Emphasis Type="Italic">q</Emphasis>

This paper proposes an extension of the minimal Hellinger martingale measure (MHM hereafter) concept to any order q≠1 and to the general semimartingale framework. This extension allows us to provide a unified formulation for many optimal martingale measures, including the minimal martingale measure of Föllmer and Schweizer (here q=2). Under some mild conditions of integrability and the absence of arbitrage, we show the existence of the MHM measure of order q and describe it explicitly in terms of pointwise equations in ? ^d . Applications to the maximization of expected power utility at stopping times are given. We prove that, for an agent to be indifferent with respect to the liquidation time of her assets (which is the market’s exit time, supposed to be a stopping time, not any general random time), she is forced to consider a habit formation utility function instead of the original utility, or equivalently she is forced to consider a time-separable preference with a stochastic discount factor.
