Pains and gains of environmental management system certification for the sustainable development of manufacturing companies: Heterogeneous effects of industry peer learning

Environmental sustainability is a growing global concern. Environmental management systems (EMS) could be an effective strategic tool to help firms deal with their sustainable development. However, whether EMS certification pays off financially and how it takes effect can be debated. Thus far, these questions remain largely under‐researched. In particular, the effects of EMS certification on financial performance are inconclusive, and the reasons explaining the effects are underdeveloped. This study aims to enrich the current research by exploring the mediating and moderating roles from the perspective of cost‐efficiency trade‐offs to reveal how EMS certification affects financial performance. Applying a PROCESS procedure analysis and causal mediation analysis to a sample of 1,751 Chinese listed manufacturing firms from 2008 to 2016, this study shows that the effect of EMS certification on firms' financial performance is insignificant because their operating costs burden increases while their marketing efficiency and managerial efficiency improve. For the first time, this study demonstrates the moderating role of industry peer learning, as the mediating effects decrease with the growth of industry peer learning.     

均衡性转移支付、公共支出结构与经济高质量发展

本文首先从理论层面系统阐述均衡性转移支付、公共支出结构与经济增长质量三者之间的多重作用机制。其次立足“五大发展理念”构建综合指标体系对经济增长质量展开测度，本文发现我国地方经济增长质量虽然在整体上呈缓慢上升态势，但其绝对水平相对偏低，且具有较为明显的地区异质性。最后本文通过构建动态面板联立方程模型与采取三阶段最小二乘法进行实证考察，结果表明：地方政府公共支出结构与经济增长质量显著正相关，但均衡性转移支付与经济增长质量的正相关关系并不显著。标准化回归结果显示均衡性转移支付能够通过优化公共支出结构对地方经济增长质量产生间接提升效应。     

基于声誉效应的工程监理激励机制模型研究

为了提高工程监理工作积极性,基于Holmstrom-Milgrom模型,引入声誉效应,建立声誉效应和显性激励机制相结合的动态委托代理激励模型。分析声誉效应发挥激励机制作用条件,并与未考虑声誉效应的委托代理模型进行比较。结果表明:声誉效应在满足一定的条件下,引入声誉激励机制能够增加业主的期望收益,并且能提高监理的努力水平。最后,通过数值仿真模拟验证引入声誉效应的合理性。     

国企利润分配制度改革与资本积累

依据鲍尔斯等学者对"剩余产品"的相关论述,本文将国企利润分配制度改革分为"利润控制主体改革"和"利润使用方式改革",按照这两个维度,立足于《资本论》中的理论与方法,建立了马克思主义理论框架,对国企利润分配制度改革作出了新的阶段划分,并解释了新中国成立以来国有工业企业的长期资本积累历程。本文的基本结论是,"利润控制主体改革"和"利润使用方式改革"均影响资本积累。当前,深化国有资本经营预算改革面临的真正挑战是预算支出结构改革将导致公平与效率的权衡,在民生支出提高的情况下需要保证国有资本经营预算的相对独立性,切实提高国有资本经营生产性支出效率。     

Analysts' Cash Flow Forecasts,Audit Effort,and Audit Opinions on Internal Control

We examine the economic impact of analysts’ cash flow forecasts by looking at how external auditors respond to financial analysts’ issuance of cash flow forecasts. Using a differences‐in‐differences approach, we find that financial analysts’ initiation of cash flow forecasts leads to reduced auditor fees and audit report lags. Moreover, after cash flow forecast initiation, firms report fewer Section 404(b) internal control weakness disclosures. These findings suggest that cash flow forecasts constrain earnings manipulation and improve management accounting behavior, thereby reducing inherent and control risk and strengthening firms’ internal control over financial reporting.     

The Effect of Leasing versus Buying on Entry Deterrence

Models of entry deterrence typically require that incumbents possess a cost advantage as a prerequisite for deterring entry. Potential entrants possess a cost advantage over incumbents, however, if input costs fall over time. This paper models the behavior of an incumbent and a potential entrant when the input cost falls over time and the firms have the option of buying or leasing the input. The model shows that if the future cost savings from new technology exceed the marginal transaction costs of leasing the current equipment, then leasing increases the incumbent's ability to deter entry.

灰灰的亲事

朋友把三三和灰灰寄养在我这儿.三三是女猫,灰灰是男猫.灰灰有点闹,他最喜欢的就是坐在窗台上看楼下的流浪猫出神,然后扯着脖子喊两声.他知道我不喜欢他喊,只要我一叫"灰灰",或者看他一眼,他就立刻把后半声咽回去,挺可怜的.     

地方政府财政支农支出与农村居民消费——来自中国29个省市面板数据的经验证据

本文在消费者最优消费路径选择的基本框架下,构建了一个政府财政支农与农村居民消费的动态最优化模型,理论分析表明:地方政府财政支农支出的增加,对于农村居民消费水平的提高具有促进作用。基于1995-2008年的省际面板数据,采用工具变量GMM方法对该结论进行的实证检验发现:在通过多工具变量克服变量内生性之后,地方政府财政支农支出对农村居民消费具有显著的促进作用,地方政府财政支农支出每增加1%,我国农村居民消费将增加0.1367%;进一步的因素分解显示,地方政府财政支农支出对农村居民消费的平均贡献度为8.72%,且有逐年增大的趋势。此外,财政支农支出对农村居民消费的影响存在区域差异性,即财政支农支出对我国中西部地区农村居民消费的影响程度大于东部地区。     

出口食品农产品检验检疫风险评价体系的建立

利用美国M IL-STD-822B标准的原理和方法构建了出口食品农产品检验检疫风险评价矩阵,首次定义了检验检疫风险事故是不合格产品引起的国内外不良反应,并制定了风险事故后果的严重等级划分标准,确立了以一年内发生风险事故的频次作为风险事故发生概率的原则;同时依据欧盟2002/63/EC指令对风险评价结果制定了以连续459批为一个监控周期的抽样方案。根据风险评价体系,将出口食品农产品检验检疫风险设置为5个风险等级：HHH、HH、H、M和L,依据监控抽样的检测结果可以对具体出口企业和产品进行风险等级加严或放宽的动态调节。
