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.     

中国—东盟自由贸易区间接税法律制度协调研究

虽然《中国与东盟全面经济合作框架协议》已经对最有可能阻碍域内货物跨境交易的关税制度进行了协调,但还远远不够,因为各国国内间接税的税制差异同样也会对相互之间的贸易往来构成障碍。中国—东盟自由贸易区要实现货物、人员、服务和资本等要素真正的全流通,还必须关注包括间接税在内的其他税收法律制度的协调。欧盟间接税法律制度协调实践为其他区域合作体提供了值得借鉴的经验,中国—东盟应结合本区域发展的特点,汲取欧盟有益的做法,逐步推进自贸区间接税税制协调工作。     

“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。     

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.     

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.

企业社会责任、现金股利与投资效率

本文选择我国2008-2016年沪深两市的A股上市公司作为研究样本,首先实证检验了企业承担社会责任对企业现金股利分配的影响。研究结果表明,社会责任表现越好的企业其更倾向于派发或连续派发现金股利,并且现金股利支付率越高。接下来本文对企业发放现金股利与投资效率的关系进行了研究。研究表明,企业发放现金股利通过减少企业的自由现金流抑制代理问题,缓解了自由现金流富余的企业的过度投资,连续派现向市场传递出的积极信号为企业带来新的融资,缓解了自由现金流紧缺的企业的投资不足。最后,本文进一步研究了企业社会责任在现金股利与投资效率的相关关系中发挥了何种调节作用,研究结果显示企业通过履行社会责任增加现金股利的发放,进而可以显著提高现金股利对过度投资的抑制作用。履行社会责任的企业更倾向于连续派现,从而提高了现金股利对投资不足的缓解程度。     

我国自贸区金融产业效率的影响因素分析

本文首先运用SFA模型计算我国11个自贸区金融产业效率,然后运用面板数据模型 实证分析金融产业效率影响因素对效率的作用。结果表明：金融产业中就业人数比固定资产投 资占有更重要的位置;对外开放程度、金融集聚程度、地方政府支持和人力资本对金融产业效 率的增长均产生显著的正向影响。     

上海自贸区跨境服务贸易负面清单制定的法律问题

上海自贸区跨境服务贸易负面清单的制定是落实《全面深化中国(上海)自由贸易试验区改革开放方案》,顺应国际服务贸易规则重构的重要举措之一。国民待遇的例外、市场准入的例外以及当地存在的要求是跨境服务贸易负面清单的涵盖范围;市场准入的例外不仅包括形式上的管理措施,还包括效果上的管理措施;当地存在与商业存在既有联系又有区别;跨境货物贸易与跨境服务贸易之间的界限值得厘清;兜底条款可纳入清单但适用应当谨慎。     

"新新贸易理论"的思想脉络及其发展

新新贸易理论将企业异质性成功的引入到国际贸易模型中,从微观层面解释了贸易的发生及影响,从而开拓了国际贸易研究的新领域。新新贸易理论解释了为什么好的企业做国际贸易,而较次的企业做国内贸易这一现象,该理论认为,自由贸易可以提高产业生产率水平和社会福利,所以在政策上应该促进自由贸易而不是贸易保护。
