北美自由贸易区经济周期协动性的实证研究

自《北关自由贸易协议》签订并实施以来,美国、加拿大、墨西哥三国间的经贸联系日益密切。三国间经贸投资联系的加强必然会作用于三国宏观经济波动的传导,并改变北美自由贸易区内美、加、墨三国经济周期协同的特点。本文首先探讨了《北美自由贸易协议》对美国、加拿大、墨西哥三国间贸易与投资的积极效应,然后对三国在北美自由贸易区成立前后的经济周期协动性变化的特征事实进行了分析,最后考察并检验了《北美自由贸易协议》对三国间经济周期协动性的影响。     

An analysis of the disruptive impact of the entry of Free Mobile into the French mobile telecommunications market

The issue of disruptive operators has recently gained interest among researchers and regulators. From a regulator's perspective, disruptive operators can increase competitive rivalry in markets dominated by a handful of large companies, thereby allowing consumers to obtain more benefits in terms of price and quality. Largely overlooked in this discussion has been the impact that the specific identity, complementary assets of operators, and their strategies have on the marketplace dynamics. In this paper we explore the impact that one such operator – Free Mobile – has had on the French mobile telecommunications market. Drawing on a wide range of secondary sources, our analysis finds that the entry and subsequent growth of Free Mobile has had a complex and multi-faceted impact on the market. Their growth has been at the expense of the other three mobile network operators active in the French market, while their innovative business model, which enables it to compete on the basis of low costs, has been copied by its rivals. The specific characteristics of Free Mobile and of its strategy have contributed to a significantly alteration to how competition occurs in this market. This, in turn, triggers a strong incentive for restructuring, which is actually restrained by regulatory concerns.     

城乡要素自由流动促进新发展格局形成的路径研究

城乡要素自由流动是畅通国民经济循环、构建“双循环”新发展格局的内在要求。从需求端看,城乡要素自由流动既有利于劳动力等要素流向城市、推进新型城镇化;也有利于高端要素回流乡村,激发乡村蛰伏的发展潜能、促进乡村振兴,从而为构建“双循环”新发展格局拓展新的内需空间。从供给端看,城乡要素自由流动有利于畅通生产、分配、流通和消费各环节,平衡城乡要素结构,提升要素配置效率,为构建“双循环”新发展格局培植新动能。因此,要发挥“有效市场”在要素配置中的决定性作用,深化城乡要素市场化配置改革,消除阻碍城乡要素自由流动和高效配置的各种体制障碍,打通“双循环”新发展格局中城乡要素流动的关键堵点。要发挥“有为政府”在乡村基础设施和政策体系制度供给中的作用,深化户籍、土地等制度改革,使城乡人口流动摆脱户籍制约,构建城乡统一的建设用地出让机制。要加大对要素返乡的支持力度,全面推进城乡新型基础设施建设,为形成“双循环”新发展格局提供有力的要素支撑。     

Efficiency vectors, efficiency and performance measures: new methods for ranking efficient organizational units

We present and discuss measures for analyzing productivity in deterministic frontier models. A new efficiency measure is introduced allowing for discrimination among efficient organizational units. In addition, a new performance measure for analyzing productivity of organizational units is presented. This measure fulfills various properties of efficiency measures but relaxes the indicator property. Both new approaches are based on the development of efficiency vectors which is a new vector measure for measuring efficiency. The vector components are efficiency measures related to subsets of a production possibility set. The new approaches are applied in the context of data envelopment analysis.

When a Loser Gains: Free Riding in the Innovation of Network Goods

We consider duopolists innovating and producing a good subject to network externalities. If successful in R&D, a firm sells both the old product and the new one. The new product increases the utility of its user; it also generates a higher network externality than does the old product. A firm which fails to innovate nevertheless profits from the success of the rival: the network effect raises the value of the old product it still produces. A firm free-rides on the innovative efforts of another firm, reducing the incentives of any firm to innovate.     

中国—东盟自由贸易区物流人才培养实施的模式与建议

中国—东盟自由贸易区将在2010年正式建立,在中国和东盟国家开展对话以来,双边的商贸物流发展很快,该自由贸易区建成以后,物流量将会更大。物流的快速增多,需要大量的物流专业人才。本文就培养中国—东盟自由贸易区物流人才的相关问题进行了研究,提出了中国—东盟自由贸易区物流人才培养的模式、实施办法、存在问题及其建议。     

Domestic entry, optimum-welfare and maximum-revenue tariffs

In this paper, we examine the ranking of the maximum-revenue tariff and the optimum-welfare tariff under a linear Cournot oligopoly model without and with free entry of domestic firms. We demonstrate that in a regulated entry oligopoly with asymmetric costs, when the marginal cost of the domestic firms exceeds a critical value, the maximum-revenue tariff is higher than the optimum-welfare tariff. We then show that under free entry of domestic firms with asymmetric costs, when the fixed cost gets larger and the domestic firms become fewer, the difference between the optimum-welfare tariff and the maximum-revenue tariff becomes larger.     

“粤港澳特别合作区”战略的理论基础与框架构想

粤港澳传统“前店后厂”的合作模式越来越不适应新形势下粤港澳区域经济一体化发展的要求。尽管CEPA使香港与内地关系越来越紧密,但仍不能满足粤港澳特定区位所要求的区域经济整合。而“粤港澳特别合作区”正是发展三地特殊合作关系的途径,是珠三角城市群一体化的必然结果,也是泛珠三角以及中国-东盟自由贸易区的最终形成的必由阶段。基于此,本文分析了“粤港澳特别合作区”形成的现实基础、必要性、存在的困难以及发展的目标模式和路径等问题。     

公司治理、债务约束与自由现金流过度投资——基于发电行业上市公司的实证研究

本文以沪深股市的电力上市公司为样本,从公司治理、债务约束机制和自由现金流量相互关系的角度实证分析了电力上市公司的过度投资行为。探讨了公司治理结构、制度环境和债务在抑制过度投资中的作用。研究结论表明：（1）我国电力上市公司存在过度投资行为,但和自由现金流的关联度并不显著;（2）公司治理特征变量与自由现金流量的过度投资行为存在显著负相关关系;（3）债务约束效应在发电行业并没有发挥应有的作用,本文从制度的角度对这一现象进行了解释。
