环境规制、技术创新与中国火电行业的效率提升

基于效率的视角,本文对2004年中国30个省(自治区、直辖市)火电行业的环境规制进行分析。首先利用三阶段DEA模型排除经营环境与统计噪音对中国火电行业效率的影响,然后从非规制、弱规制、强规制三个层次分析环境规制程度与中国火电行业效率的关系。实证结果表明,环境规制可以提升中国火电行业整体的效率水平,总体上存在技术创新激励效应,但并非适用各个地区。最后本文根据环境规制与技术效率的关系,将中国各地区火电行业的发展模式划分为内力驱动环境友好型、环境弱友好型和外力推动环境友好型三种,并给出各自适应的规制建议。     

限额存款保险与中国银行业的市场约束

一般认为,限额存款保险制度让存款人的资产部分地暴露于风险之中,从而市场约束虽然比无保险状态下较弱但仍然有效,因此世界上实行存款保险制度的国家多采用限额保险。本文认为,中国银行业特殊的股权结构,以及长期以来政府对大银行的资金支持形成了存款人规模偏好和银行大而不倒(too big to fail)的预期;这一预期特征必将异化市场约束,进而导致银行陷入无序的规模竞争并激励其风险承担;如果单纯实施限额存款保险制度,非但不能修正中国商业银行市场约束的异化问题,而且将强化公众的大而不倒预期,使市场约束面临更严重的扭曲。     

经销关系中双边道德风险的一种契约解决机制

对于需要进行专用性资产投资或通过契约安排形成专用性资产投资的经销关系中,往往会存在双边道德风险:一是生产商敲竹杠的道德风险;二是经销商隐蔽行为的道德风险。本文通过一个简单的不完全契约安排试图解决这种双边道德风险,以取得社会最优投资,促使交易的完整进行。     

Carbon taxes and the double dividend hypothesis in a recursive-dynamic CGE model for Spain

A carbon tax is potentially a policy that can reduce CO₂ emissions and mitigate climate risks, at lowest economy-wide costs. We develop a dynamic CGE model for Spain to assess the economic and environmental effects of a carbon tax, and test the double dividend (DD) hypothesis. We simulate the impact of three carbon taxes: €10, €20 and €30 per ton of CO₂. For each tax, four ‘revenue recycling’ scenarios are examined: a reduction of taxes on capital, on labor, on value-added tax, and a scenario in which revenues are not recycled. We find a DD for taxes of €10/ton and lower, within five to seven years of implementation. We estimate an annual CO₂ emissions reduction of around 10% with this tax. Under some circumstances, the DD can be achieved for a tax of €20/ton. In any case, recycling revenues to cut pre-existing taxes reduces costs of imposing carbon taxes.     

Proposition of a structural model for business value creation based on circular business models,innovation, and resource recovery in the pet industry

Based on the assumptions of circular economy, resource recovery, and innovation, the aim of this research is to analyze the relationship between innovation constructs, resource recovery practices, Circular Economy Business Models (CEBMs), and value creation in a fast-growing emerging economy. A set of empirical data from 443 companies in the pet industry were used. In terms of methodology, the study was processed using the SPSS software, using Structural Equation Modeling, with manipulation of primary data. CEBMs demand greater engagement, internalization of initiatives, and synergy with the operating ecosystem of the pet industry. Innovation is present but has the potential for expansion through adherence to the innovation ecosystem and its technological package, partnerships, and relationships so that companies can scale up and create value with the support of resource recovery practices. The results of this study can be useful for companies in the pet industry, as it allows the identification of areas and practices that require their attention to improve organizational performance and create value for the business based on initiatives supported by the assumptions of circular economy and sustainability.     

企业慈善行为测量及其对员工职场精神力的影响

针对现有企业慈善行为测量单一化、短期化与外部化的局限以及从内部员工视角研究慈善战略价值的欠缺,开展了两个关联研究。在研究一中,采用归纳法开发并检验了一份包含内外部慈善的日常性企业慈善行为量表。结果显示,企业慈善行为具有一阶双因素结构,由外部慈善行为与内部慈善行为因素构成。该量表信效度较好,可用于实证研究。在研究二中,检验了企业慈善行为对员工职场精神力的影响,结果显示内外部慈善均对员工职场精神力有积极作用,其中内部慈善行为作用更强。员工的"与组织价值观一致"相对"团体感"和"工作意义"被企业慈善行为解释的程度最高,表明企业慈善行为受到了员工高度的价值认同。     

农业名牌战略实现路径研究

实施农业名牌战略、提高农产品市场竞争力,是实现农民增收、农业增效、农村经济全面发展的重要措施.要实施农业名牌战略,必须实现农业名牌产品的质量标准化、生产规模化、保护法制化.质量标准化是农业名牌产品质量和安全的重要保证;生产规模化是质量标准化的保证和名牌成功与否的重要标志;建立健全名牌农产品的法制化保护机制,是实施农产品名牌战略的制度保障.     

中国生猪生产的区域效率差异及其适度规模选择

运用DEA方法,测算了我国散养、小规模、中规模和大规模四种生猪饲养模式的生产效率。结果表明：2002—2010年生猪生产效率的提高主要依靠要素投入规模的扩大,技术效率的贡献次之;不同省份间不同养殖规模下的生猪生产效率及最优规模存在差异。研究认为各地要因地制宜地选择适度的养殖规模。     

Estimating Market Power in the South African Banking Sector

Indicators of market power can be ambiguous because cost economies associated with scale and not market imperfections may influence results. This article illustrates that without direct measures of concentration, estimates of costs, scale economies and profitability can be used to identify market power in banking. Secondly, via this method, econometric estimates provide meaningful evidence of market power in the South African banking sector over the study sample period (1979–1998). A reasonable conclusion is that while industrial structure is important, careful consideration needs to be given to cost economies and profitability when assessing market power. In addition, there is a need to consider appropriate policy to reduce market power in banking in South Africa.     

中部农区农户打工地城镇规模类型——以河南省三个样本村为例

对农户打工地城镇规模类型的研究是认识农民工流动规律的重要内容.基于入户调查数据,采用多值逻辑回归模型和有序逻辑回归模型,以河南省三个样本村为例,对中部农区农户打工地城镇规模类型进行了研究.研究发现,农户打工地主要集中于省城、深圳经济特区、乡镇和地级市,而在县城打工的人较少;农户对打工地城镇规模类型的选择与打工距离密切相关;家庭代数、村经济发展水平和关系网络是影响农户打工地城镇规模类型选择的重要因素.
