Corporate statement serving as information subsidies in the product-harm crisis

This study explores the attributes of a crisis statement which influence its utility as an information subsidy in the process of product-harm crises in China. Through investigating and analyzing 92 statements released in times of product-harm crises, the results show that the form in which the statement is released, and the length of the statement have significant effects on whether the statement will be quoted fully or partially by the news media.     

An assessment of GRAI Grids and their use in the Strathclyde Integration Method

The purpose of this paper is to present a critical assessment of GRAI Grids as a tool for improved manufacturing integration. GRAI Grids, a key component of the GRAI approach, form an integral part of the Strathclyde Integration Method SIM for manufacturing integration. The contribution of the paper is thus to provide a 'third party' view of the effectiveness of GRAI Grids as a modelling tool. The paper presents a brief overview of the GRAI approach, concentrating particularly on the Grids, and an overview of SIM, showing how GRAI Grids are used. The main section of the paper presents an assessment and critique of GRAI Grids. Several benefits and limitations of the Grid as used in SIM and some suggestions for extensions are presented. The paper concludes that the use of the GRAI Grid, within a methodology, provides a unique insight into the behaviour and design of manufacturing information systems and that those who criticize the technique perhaps do so from a lack of awareness of its concepts, principles and advantages.     

加拿大环境保护法的变迁:1988—2008

加拿大环境保护法自1988年产生之后,随着社会环境的变化而不断更新,在正当的法律程序的指引之下,既重视法律文本的完善,又关注法律的实效,以此为借鉴,中国环境法在修改过程中,可以突出以下方面:一是进一步充实立法原则;二是建立环境保护责任制度;三是完善立法程序和立法技术.     

An Examination of How Supervisors Influence Their Subordinates to Engage in Environmental Behaviors

Employee engagement in environmental behaviors is an important topic in operations management. Drawing upon stakeholder, commitment, and organizational support theories, this study creates and tests an empirical model of how store managers (i.e., supervisors) influence their direct reports (i.e., subordinates) to become engaged in environmental behaviors. Based on a dataset derived from supervisors and their subordinates who are employed at the same grocery store location across a large retail grocery chain, we test our study's nomological model and find support for the linkages proposed. Key research and managerial implications are discussed.     

Effect of Inventory Information Discrepancy in a Drop‐Shipping Supply Chain

This article investigates the impact of information discrepancy between a drop‐shipper and an online retailer on the drop‐shipping supply chain performance. The inventory information misalignment between them contributes to the failure of order fulfillment and demand satisfaction, and hence the associated penalties are incurred. In this article, we first analyze the penalties of ignoring such information discrepancy on both the drop‐shipper and the online retailer. We then assess the impact of information discrepancy on both parties when the drop‐shipper understands the existence of the information discrepancy but is not able to eliminate the errors. The numerical experiments indicate that both parties can have significant amount of the percentage cost reductions if the information discrepancy can be eliminated, and the potential savings are substantial especially when the errors have large variability. Furthermore, we observe that the online retailer is more vulnerable to information discrepancy than the drop‐shipper, and the drop‐shipper is likely to suffer from the online retailer's underestimation of the physical inventory level more than the problem of its overestimation. Moreover, even if eliminating errors is not possible, both parties could still benefit from taking the possibility of errors into consideration in decision making.     

环境信息披露的污染减排效应评估

本文利用我国2008年正式实施环境信息披露制度这一外生冲击构造准自然实验,基于2004-2017年我国285个城市的面板数据,通过双重差分法系统评估环境信息披露对工业污染物排放的影响。克服环境信息披露的测量困难与内生性问题,首次考察环境信息披露的污染减排效果,并借助数理模型对其影响机制进行规范阐释。研究发现,环境信息披露能够显著降低工业污染物排放水平,且该影响具有一定的时滞性和长期性;同时,减排作用会随地区环境污染程度和环境规制力度的增强而呈现递增规律;此外,机制分析的结果表明,其传导机制主要来自于产业结构转型和减排技术进步。为验证研究结论的稳健性,本文提供了平行趋势、工具变量、安慰剂等多种方法的检验结果。本文的研究在经验上丰富了环境信息披露与环境污染治理之间关系的相关讨论,为提升我国环境污染治理水平、打赢污染防治攻坚战提供有益的政策启示。     

财政分权和环境规制促进了中国绿色技术创新吗？

基于我国2003-2017年省级面板数据测算财政分权水平和财政分权效率,结合两阶段关联网络DEA测算绿色创新效率、绿色技术研发效率、绿色技术成果转化效率。结合理论模型与实证模型,分析了财政分权、环境规制对我国绿色技术创新的影响。结果表明：从整体上看,财政分权水平、财政分权效率和环境规制都是推动我国绿色创新发展的积极因素,财政分权还通过影响环境规制对绿色技术创新产生积极间接影响;但也导致了地方政府不注重绿色研发的短视行为。从不同时段看,财政分权和环境规制对绿色创新影响发生了变化,一是国际金融危机以后,财政分权加大了经济刺激政策对绿色创新发展的挤出效应,但这在新时代以后得到缓解;二是2013年以后地方环境规制水平提升过快,在一定程度上反而不利于绿色创新。从发展处于不同分位的地区看,财政分权对高、低分位地区绿色创新发展支持都稍显不足,但提高财政分权效率则能显著带动高分位地区发展;环境规制只在高分位地区促进了绿色创新发展,但对绿色创新效率较低的地区而言,过高的环境规制并没有实际意义。     

中国上市 ITO 企业经营效率评价及影响因素分析

运用基于规模报酬可变的投入导向的超效率DEA模型,对在沪深两市上市的具有代表性的30家中国ITO企业的经营效率进行实证研究,结果表明中国上市ITO公司整体运营效率不高,且各企业之间存在显著差异性。为分析企业规模、员工素质、研发投入等因素对中国上市ITO企业效率的影响,采用Tobit模型发现企业规模、员工素质、政府支持等因素对企业运营效率有着积极地影响,而研发投入对企业运营效率的影响并不显著。     

Temporal Disaggregation: Methods,Information Loss,and Diagnostics

This research provides a generalized framework to disaggregate lower-frequency time series and evaluate the disaggregation performance. The proposed framework combines two models in separate stages: a linear regression model to exploit related independent variables in the first stage and a state–space model to disaggregate the residual from the regression in the second stage. For the purpose of providing a set of practical criteria for assessing the disaggregation performance, we measure the information loss that occurs during temporal aggregation while examining what effects take place when aggregating data. To validate the proposed framework, we implement Monte Carlo simulations and provide two empirical studies. Supplementary materials for this article are available online.
