我国风力发电项目投资风险评价——基于支持向量机模型

在分析我国风力发电项目投资风险并建立其评价指标体系的基础上,将支持向量机模型用于风力发电项目投资风险评价,全面衡量风力发电项目面临的经济风险、技术风险、政策风险等。支持向量机方法很好地解决了风力发电项目样本数据缺失、评价主观性问题。实证分析结果表明,利用支持向量机模型评价风力发电项目的投资风险,具有一定的适用性和准确性。     

自恋领导对下属绩效的影响研究：基于关系视角

近年来,在领导特质研究领域,自恋领导得到了学者的广泛关注。尽管现有研究探讨了自恋领导对下属的影响效果,但鲜有研究从领导与下属人际互动视角揭示自恋领导的作用机制。本研究基于领导特质过程模型和权威互补理论,探讨自恋领导对下属绩效的影响,并挖掘其内在影响机制以及作用边界条件。通过对一家保险公司进行多时点、多来源的问卷调查,研究结果表明：自恋领导对下属绩效具有显著的负向影响;关系冲突在其中起中介作用;下属权力距离负向调节了自恋领导与关系冲突之间的正向关系,即下属权力距离越低,自恋领导与关系冲突的正向关系越强,反之则越弱。此外,当下属权力距离较低时,关系冲突的中介作用更强,反之则被削弱。     

Does oligopsony power matter in price support policy design? Empirical evidence from the Thai Jasmine rice market

In the oligopsony market, farmers may receive low prices and policy analysis assuming perfect competition can yield serious bias results. In this paper, we estimate oligopsony power between processors and farmers and evaluate the welfare impact of the paddy pledging program (PPP), a generous price support program in the Thai Jasmine rice market, with an imperfect competition model. We develop a model that consists of rice supply equation and derived demand equation. We then simultaneously estimate these equations using system estimation methods to recover oligopsony power parameters. Finally, we use these parameters to assess the welfare impact of the price support program. Using annual panel data running from crop marketing year 2001/2002–2015/2016 and exploiting the institutional feature of the PPP, we find strong evidence of some oligopsony power, a moderate level of oligopsony price distortion, and a negative relationship between price support and oligopsony power. We also find that the PPP is inefficient but effective in income redistribution. Moreover, the program benefits both farmers and consumers. With better policymaking decisions, the PPP can be efficient by setting a suitable support price. Therefore, our results show that in the case of the Thai Jasmine rice market, the generally accepted “wisdom” about agricultural price support policy does not necessarily hold, and price support can be designed to improve the efficiency of the market.     

土地产权三维界定的技术路线及其评论

研究目的：对已有研究文献涉及土地产权三维界定的技术路线进行结构性把握,梳理研究脉络与趋势,以期为土地产权三维界定在研究方法和范式上的改进提供思路。研究方法：文献分析法、比较分析法。研究结果：从理论基础、界定起点和界定方案看,国内外学界对土地产权三维界定大致存在三条技术路线：基于空间分离原理的技术路线、基于空间区分原理的技术路线和基于三维地籍原理的技术路线,分别反映了法学和地籍学对土地产权形态和产权客体进行三维界定的技术方案。研究结论：未来应将土地产权形态与产权客体三维界定统一起来,厘清其内在逻辑与生成路径,深化三维土地产权客体特定化实现机制、国家公权力植入三维土地产权实现机制和三维土地产权排他性支配机制研究,加快构建三维土地产权范式。     

中国生物质发电产业发展动力因子研究

介绍了中国生物质发电产业的市场环境和政策环境。基于此,识别生物质发电产业发展的内生动力因子和外源动力因子,并利用计量经济学理论对动力因子的相关性进行分析。建立解释结构模型研究动力因子之间的关系,分析经济要素之间的作用机理。结果表明:所有的动力因子通过不同的途径和方式最终指向政策和资源禀赋因子;能源安全因子、环境保护因子、农村发展因子影响电力需求,投资影响电力供给;合理的要素成本价格需要科学的政策组合进行有效支持。     

员工发展通道模型及其自适应性研究

本文以电力企业为研究对象,研究发现影响企业员工职业发展的诸多因素,通过内部工作分析、外部标杆法等方法构建纵向延展、横向打道、多通道的企业员工职业发展通道模型,并特别提出构建与职业发展通道模型各层级及岗位群相对应的层级标准模型的重要性.同时对员工职业发展通道模型的自适应性进行深入研究,发展通道对外与企业发展环境的自适应性,对内与企业业务发展需求、核心人才需求及员工个人发展需求的自适应性,以此为基础构建员工职业发展管理的自适应机制,为建立能够快速适应市场变化、企业战略发展的职业发展通道模型奠定基础,并通过此模型的管理应用,为企业在竞争日趋激烈的生存环境中,吸引、留住、培养亟需的核心人才队伍奠定了基础.     

Investment and technological choice in a right-to-manage model

We analyze the interactions between investment and local wage bargaining in a putty-clay model where the investment decision commits the firm to a particular capital intensity. This technological precommitment is used strategically in order to manipulate the bargaining outcome. We show that this strategic behavior induces a nonmonotonic relationship between the capital and labor demands of the firm and most of its environmental parameters (e.g., the bargaining power of the union, its minimum wage requirement, the capital cost). The results we obtain in our putty-clay framework thus contradict several conclusions of the standard literature on wage bargaining and investment.     

Has Austria’s Accession to the EU Triggered an Increase in Competition? A Sectoral Markup Study

We estimate the pro-competitive effects of Austrias participation in the Single Market after its European Union (EU) accession in 1995 in terms of firms market power as measured by the Lerner index, using a sample of 46 industries and 7 industry groups, covering the period 1978–2001. In the framework of the markup estimation method suggested by Roeger (1995), we test for both an instantaneous structural break between 1993 and 1998 and also estimate logistic smooth transition models to take up the proposition that the regime shift is likely to have occurred gradually rather than as a big bang. In sum, the results provide no reason for being euphoric: Pronounced markup reductions were only found in three industry groups (mining and quarrying, wholesale and retail trade; financial services and real estate). At the more disaggregate level, the picture is mixed: Both increases and reductions in market power have been found.     

我国产业集群的竞争力研究

Industrial clusters have been an important phenomenon of the global economy.
