Environmental sustainability practices and exports: The interplay of strategy and institutions in Latin America

We integrate institutional economics with stakeholder theory to examine the antecedents and outcomes of Environmental Sustainability Practices (ESP) for small and medium enterprises in Latin America. We find that these firms primarily engage in ESP to succeed in export markets. We also find that this is especially true when firms demonstrate organizational agency by adopting complementary strategies such as obtaining international quality certifications to develop credibility among stakeholders. Lastly, their cause receives a further boost when they are based in institutional environments that are known for strong democratic voice and accountability mechanisms. In elucidating the interplay of strategy and institutions, we suggest the need to better integrate organizational agency into institutional theory and institutional environment into stakeholder theory.     

How resilient is La Réunion in terms of international tourism attractiveness: an assessment from unit root tests with structural breaks from 1981-2015

Even if local policymakers increasingly claim that tourism is one of the key factors of future economic development for the French small island La Réunion, international tourist arrivals are observed to be locked in a stagnation phase since the beginning of the 2000s. Starting from this stylized fact, this article aims to study if this phenomenon results from major external events hurting this economy regularly. Next, by using univariate unit root procedures with structural breaks, we test for evidence of permanent or transitory effects of external shocks on international tourist inflows (total, by source markets, and by category) over the period 1981–2015. Finally, the empirical analysis allows us to reject the null of a unit root. Then, stagnation of tourism arrivals to La Réunion is not due to exogenous shocks but probably results from endogenous impediments within the domestic tourism industry and unsuitable public policies.     

战术面向服务架构概念及相关技术

战术面向服务架构（TSOA）是实现战术云平台服务基础设施的重要支撑概念。由于战术环境的复杂性，目前对TSOA实施过程中面临问题和相关实现技术的总结还较少。为此，开展了针对TSOA的概念以及相关技术的研究。首先，从战术环境下的TSOA架构需求背景出发，介绍了TSOA架构的组成以及适应性特征；然后，通过分析战术环境下设备和网络等多方面存在的限制性因素，明确实施TSOA架构所面临的挑战以及需要解决的关键问题，并对实现过程中涉及的服务发现、消息传输机制、网络状态自适应等相关技术进行归纳；最后，对国内外的相关研究工作进行总结，期望对推动TSOA架构的具体实施提供一定参考。     

投桃何以报李:企业内外部社会责任对管家行为的影响机制研究

当员工感知到企业的善行,即企业善待员工或是积极履行对外部利益相关者的责任,是否会激发员工"舍己为公"的行为倾向,使其为了保护组织长远利益而牺牲个人短期利益呢?本研究依据社会交换和社会认同理论,通过524份有效样本进行实证分析,探讨员工感知的企业社会责任对"舍己为公"的管家行为的作用机制。结果表明,员工感知的内部和外部企业社会责任均正向影响员工的管家行为。责任知觉和道德认同分别在员工感知的内部企业社会责任与管家行为、员工感知的外部企业社会责任与管家行为间起中介作用,且责任知觉和道德认同的中介作用没有显著差异。     

市场环境、企业社会责任与基金安全投资转移

当市场环境不好以及不确定性增加时，基金进行安全投资转移。企业积极履行社会责任所形成的声誉资本具有“类保险”作用，在面临负面事件或不确定性环境冲击时能够防止股价大幅下跌和市值损失；基金是否会在市场环境不好时将投资组合转向社会责任绩效更高的股票进行安全投资转移呢？使用2010—2017年开放式基金样本，实证检验了企业社会责任、市场环境与安全投资转移之间的关系。研究发现，在市场环境表现不佳时，基金避险需求增加，倾向将投资组合更多地转向社会责任绩效高的股票进行安全投资转移；进一步研究发现基金和基金经理特征影响基金的安全投资转移行为，净资金流入较少、历史业绩差、经理选股能力差的基金根据企业社会责任进行安全投资转移的程度大。研究还发现，基金的安全投资转移行为对基金业绩和基金收益波动产生了积极影响。     

公司诉讼风险对审计决策的影响研究——基于异常审计费用和审计意见的证据

近年来上市公司诉讼风险不断攀升，对审计师决策行为的影响日益凸显。基于这一背景，系统探讨公司诉讼风险对审计决策的影响，分别研究公司诉讼风险对审计费用决策和审计意见决策的影响，并考察在诉讼风险冲击下审计费用决策和审计意见决策间的关系,同时结合我国制度背景，研究法律环境差异性对两种决策之间关系的影响。研究发现：公司诉讼风险越高，审计师收取正向异常审计费用的概率越高，出具非标准审计意见的可能性越大；审计费用策略和审计意见策略之间存在替代关系，即审计师倾向于在出具标准审计意见时收取正向异常审计费用作为风险补偿。进一步研究表明，在外部法律环境薄弱地区，审计费用决策和审计意见决策之间的替代关系更加显著。研究结论有助于合理解释和评价审计师的决策行为，对监管机构规范审计师的行为有着一定的启示意义。     

浅谈城市河道水环境综合整治

河道水环境对城市生态环境建设有着十分重大的意义。城市河道水环境综合整治正在不断壮大规模,现阶段正在朝着防洪固堤、水质提升、水环境改善方向发展,并且城市河道水环境的综合整治还要求对城市污水排放进行严格化管理,防止生活用水和工业污水对河道造成污染。论文主要对当前城市河道水环境存在的问题进行探讨,并对当前存在的问题提出一些具有针对性的解决措施。     

Considering the nuclear option: Hidden benefits and social costs of nuclear power in the U.S. since 1970

Although burning fossil fuels has environmental consequences, many countries have switched away from nuclear power in favor of fossil-fuel fired electricity production after incidents at Three Mile Island, Chernobyl, and Fukushima. This study estimates the substitution between nuclear and fossil-fuel fired electricity generation in the United States. Using an event-study framework, we leverage nuclear plant openings from 1970 to 1995 and forced nuclear plant outages from 1999 to 2014. Plant openings (nuclear outages) reduce (increase) monthly net coal-fired generation by approximately 200 GWh, implying a considerable reduction (increase) in emissions. We find that the substitution between nuclear and coal is not one-to-one, as has been assumed in prior literature. After establishing these stylized facts, we explore the potential underlying forces driving the observed substitution between coal and nuclear.     

营商环境优化能够提升全球价值链分工地位吗*

本文基于世界银行发布的历年营商环境报告相关数据，从OECD ICIO提供的基础数据测算结果的基本事实出发，理论阐释了营商环境对攀升全球价值链的影响及可能机制。以此为理论先导，进一步利用跨国面板数据的计量检验发现：第一，营商环境优化的确对价值链分工地位具有显著正向作用；第二，上述正向作用不仅来自营商环境优化直接效应，而且还通过价值链迁移、创新活动激发、贸易条件改善等中介作用形成间接效应。据此，打造国际一流营商环境对促进中国攀升全球价值链具有重要支撑作用。     

自治、博弈与激励:我国农村人居环境污染治理的制度安排

基于中央政府、地方政府及农民的互动视角,采用博弈分析方法,系统考察了我国农村人居环境污染的逻辑机制。研究发现:我国农村人居环境污染的根源在于规制失灵;农村人居环境公共资源的“公地悲剧”不是必然现象,可以在农民之间建立一种自实施的自治机制,避免导致“公地悲剧”;由于利益目标的差异,中央政府与地方政府之间的激励问题、地方政府与农户之间的博弈行为,导致了农村人居环境规制失灵。研究启示是,制度的建立健全是农村人居环境治理顺利推进的保障,更将有利于乡村振兴战略的实施以及我国农村的可持续发展。
