试论循环经济价值链及其运行

企业必须按照自然生态体系，将经济活动高效有序地组织成一个循环经济模式，实现以最小的资源消耗，最小的污染获取最大的发展效益。循环经济的正常运行，必须有价值链的支持，因此，循环型产业的价值形成机制是循环经济持续发展的关键。企业是实施循环经济的最终策动力和执行主体。因此，循环经济特别是循环经济价值链能否形成已成为企业持续发展的重要因素。     

国有公司财务监督问题研究

现行的国有公司财务监督中缺少真正代表国有资本所有者行使监督职权的机构和人员，董事会、监事会和财务人员管理体制的缺陷以及外部审计监督的不力使得国有公司经营管理者有机会违规获取个人利益，结果必然导致国有资产流失。应考虑建立国有公司出资者监督代表的再监督制度和对财务监督人员的激励约束制度，推行国有公司年报审计的公开招标制。     

会计师事务所与客户的双边匹配

以2013年至2018年A股上市公司及为其提供审计服务的国内会计师事务所为研究样本,基于双边匹配理论探讨了审计市场中会计师事务所与企业之间的匹配情况对审计质量和审计风险的影响。研究结果表明,综合实力较强的会计师事务所倾向于与综合实力较强的企业进行匹配,呈现出审计双方综合实力相当的一种正向类聚匹配：当双方匹配程度越高时,企业可操纵性应计利润较少,审计质量越高;同时,当审计双方匹配度越高时,审计风险越低。上述结果证实了审计市场上会计师事务所与客户匹配的有效性和重要性,并对通过双边匹配提高会计师事务所的审计质量、降低审计风险,为审计市场资源优化配置提供了理论指导。     

一种适用于高铁沿线的多台站快速地震预警方法

对于地震预警技术来说,根据参与监测预警的台站数量不同,可以将高速铁路地震监测预警系统分为单台站地震P波预警技术和多台站地震P波预警技术。单台站P波预警由于信息量较少以及噪声影响,在定位方面存在较大误差。多台站P波预警技术是在单台站P波预警的基础之上,综合多个单台站信息进行综合震源参数估算并发出地震预警信息的预警方式。通过应用多台站P波预警定位技术,能够在震源估算方面得到更准确的结果。     

Labor unemployment risk and firm risk

This paper examines the effect of labor unemployment risk on firm risk. Using unemployment insurance benefits as a proxy for unemployment risk, we find an economically significant positive relation between unemployment risk and firm risk. This positive relation is more pronounced for firms that are more labor-intensive, have a higher layoff propensity and are more financially constrained. While existing literature that employs corporate policy measures such as debt and cash holdings suggests an opposite relationship, our paper presents evidence that the effects stemming from earnings management, earnings quality and reporting quality appear to dominate.     

Mixed Duopoly,Merger and Multiproduct Firms

The literature on mergers has extensively analyzed the decision to merge by private firms, but it has not considered the decision to merge by private and public firms. We assume that when a private firm and a public firm merge (or when one of them acquires the other), they set up a multiproduct firm in which the government owns an exogenous percentage stake. In this framework, we show that the decision to merge by firms depends on the degree to which goods are substitutes and on the percentage of the shares owned by the government in the multiproduct firm.     

Teams, Firms and the Evolution of Profit Seeking Behavior

Even as advances in information theory over the last quarter century have cast increasing doubt on the proposition that firms successfully maximize profits, the objective of profit maximization continues to be an axiomatic feature of the neoclassical theory of the firm. This paper attempts to improve our understanding firms by treating the objective function as an open question. Specifically, an ontogenetic thought experiment is undertaken to address the question of what differentiates production teams from firms by asking why team members would sell their control rights to a principal, thereby transforming the team into a firm. What results is an account of the emergence of the objective of profit seeking. Profit seeking emerges endogenously as a more fit alternative than the objective of value maximization, which is less capable of coping with uncertainty through purposive adaptation.     

Policy options for afforestation in Flanders

This paper analyses current and alternative afforestation policy instruments in Flanders. First we select forest sites that maximize net social benefits given a constraint on the total area of new forests and then we select policy instruments that yield this optimal combination of sites. For each policy option, we calculate the associated costs for landowners and government as well as net social benefits for society. Our empirical illustration shows that the welfare gain is considerable if the afforestation subsidy is conditioned on an objective criterion rather than a case-by-case approach. Our results also show that it is worthwhile to consider alternative policy instruments, such as auctions, not previously used in Belgian legislation.     

企业网络组织协同竞争的理论与效应解析

竞争与合作相统一的协同竞争已成为企业网络竞争战略发展的必然趋势。通过对企业网络组织协同竞争研究脉络的梳理，可构建协同竞争研究的评析架构。其理论演进是：以系统思维作为理论逻辑的基点，以合作竞争为行动策略，以价值创造作为网络协同竞争的本质属性；在实践效应上，协同竞争具有提升竞争优势的特征，而博弈模型对协同效应发挥着解析工具的作用。     

The Downside of Knowledge Spillovers: An Explanation for the Dispersion of High-tech Industries

Both theoretical work on knowledge spillovers and regional policy initiatives often assume that there exists a general and unanimous advantage for firms to cluster. But opposed to the benefit is the disadvantage of sharing knowledge with other (rival) firms. This paper highlights the “downside” associated with knowledge spillovers and presents a four-stage game of location choice where spillovers result from labour poaching and where the strategic interaction between firms may make them avoid co-location with spillovers. The model provides an explanation for the dispersion of German high-tech industries found in a companion paper.
