国外证券业规制研究：综述与启示

证券业作为金融行业的重要组成部分,在整个国民经济中占有重要地位。任何一个存在证券市场的国家无一例外地存在明显的政府规制,各国均从各自的实际情况出发,对证券产业的进入、价格、退出等方面采取了一定的规制措施,以确保金融和经济体系的稳定。本文从国外的研究成果中得到启示,希望以此对我国的证券业规制实践活动起一定的指导作用。     

预算软约束、企业财务风险与审计定价

本文具体考察在上市公司存在预算软约束的情况下,我国的会计师事务所在审计定价时如何考虑上市公司的财务风险.研究结果表明:①事务所的审计收费与上市公司的负债比率之间呈显著的正相关关系;②在国有上市公司中,预算软约束程度的增加降低了公司的财务风险,因此审计收费与公司负债比率之间的正相关关系有所减弱;③在金融发展水平比较高的地区,预算软约束程度的减轻提高了公司的财务风险,因此审计收费与公司负债比率之间的正相关关系有所增强.这一研究结果说明,我国的会计师事务所在审计定价时不仅考虑了上市公司的财务风险,而且还会根据公司的预算软约束程度对其财务风险进行相应的调整.     

The Importance of taste in experimental auctions: consumers’ valuation of calorie and sweetener labeling of soft drinks

A majority of purchases that consumers make are classified as repeat purchases. One of the main reasons why consumers make repeat food purchases is the food's taste. Therefore, we examined the importance of including taste testing in nonhypothetical experimental auctions. Specifically, we used two experiments to determine consumers’ willingness to pay for soft drinks labeled with different calorie and sweetener information. In Experiment 1, participants tasted the soft drinks prior to the bidding rounds. In Experiment 2, participants did not taste the soft drinks prior to the bidding rounds. Bidding behavior for the soft drinks was significantly different between Experiment 1 and Experiment 2. Results suggest that including taste testing in the design of experimental auctions is important to accurately capture consumers’ willingness to pay for foods that are purchased repeatedly. Results also imply that policies aimed at combating obesity by making the calorie content of foods more visible may not produce desired outcomes.     

要素导向的大尺度城市设计编制流程及控制方法研究——以天津滨海核心区西部城区实践为例

2017年实施的《城市设计管理办法》为中国城市设计带来了新的机遇,同时也因将研究重点转向更大的尺度而给相关实践带来了新的挑战。为此,以天津滨海核心区西部城区为例,提出了基于要素控制并结合城市发展时序的大尺度城市设计编制流程。首先编制区域控制性城市设计,重点塑造区域整体结构和空间秩序,形成理想化的设计蓝图;进而编制实施性方案,落实控制性方案的设计策略并面向区域现状和实际需求进行深化调整;最终面向近期开发地块,编制开发建设方案,指导具体建设。同时对城市设计的要素控制方法进行了探讨,结果显示,编制流程和要素控制机制可使大尺度城市设计的理想蓝图层层深入,逐渐走向对具体地块的开发引导,完成从整体结构控制到项目建设方案控制的过程。     

Land-property markets and planning: A special case

Land use policy often intervenes in land-property markets. This raises a question that may have critical implications for land use policy: are these normal markets? This paper addresses that question: are land and property ordinary market goods, or do they lack some of the preconditions necessary for markets to work properly? We find that land-property has limited substitutability, due to the critical factor of location; qualified by location, land is limited and sometimes unique. These attributes make land and property investment assets risking speculation, warranting public intervention to mitigate negative social consequences. Land-property markets need market or administrative support to work, which planning provides through public and private agents. The paper reviews the different forms of planning and development control in land-property markets.     

Protected Geographical Indications and Designations of Origin: An Overview of the Status Quo and the Development of the Use of Regulation (EC) 510/06 in Europe,With Special Consideration of the German Situation

This article gives an overview of the current use of the European system of protected designations of origin according to Council Regulation (EC) 510/06, using the example of Germany to demonstrate its implementation as well as evaluating the potential and future development of this system of protection. The considerations show that in a few years the number of protected products in Europe will reach a figure of over 1,000 without the dynamic of new registrations weakening in the midterm. In Germany, the system of Council Regulation (EC) 510/06 has not been used very extensively. Despite this, an increase in the number of protected products can also be expected in Germany due to the promotion orientation of the Central Marketing Association and the European Commission.     

创新生态系统视角下价值共创如何影响企业创新绩效——一个有调节的中介模型

以创新生态系统为视角,引入创新资源互动与生态系统规范机制为中介变量和调节变量,探究价值共创如何影响企业创新绩效。基于307家企业样本数据,运用结构方程模型、Bootstrap和层级回归方法对数据进行分析。研究发现：创新生态系统中,价值共创不完全直接影响企业创新绩效;创新资源互动部分中介价值共创对企业创新绩效的影响;生态系统规范机制部分正向调节价值共创对创新资源互动的影响。最后提出,创新生态系统调控方与企业要差异化地制定提升创新绩效的实施方案,营造活跃的创新资源互动氛围,形成并完善系统内生态规范机制。     

Strategic Regulation Policy in the Internet

Some countries are importers while others are exporters of global backbone connectivity. At the same time, input components such as local access are non-traded. This paper analyzes a non-cooperative regulatory game between importing and exporting countries, assuming that the prices of both traded and non-traded inputs can be regulated. We show that exporting countries choose a more restrictive regulation of non-traded goods than importing countries do. We further show that a requirement of international non-discrimination may hurt importing countries, and give firms producing traded inputs incentives to invest in quality degradation.     

Externalities, efficiency, regulation, and productivity growth in the U.S. electric utility industry

This paper examines the decomposition of total factor productivity growth for firms subject to regulation, given the production of a bad output. The production of good and bad outputs provides benefits and costs to society. Corporate socially responsible firms recognize the cost to society of producing the bad output. The paper separates the production technology and regulation effects from both the scale and technical change components. The paper also examines the measurement and decomposition of productivity growth when not accounting for production of the bad output. Using a 1992–2000 panel of 34 U.S. investor-owned electric utilities, results indicate that improvements in the scale, efficiency change, and technical change components contributed to positive growth. Not accounting for production of the bad output led to, on average, an overestimation of both the rate of productivity growth, and the contributions of scale economies and technical change to changes in productivity growth.

市场分割条件下的混合所有制经济竞争模型与规制策略

通过构建市场分割条件下的混合所有制经济竞争模型,本文对全国性国有企业在中国改革发展过程中的作用提供了新的解释。全国性国有企业在参与区域竞争的过程中,具备一种区域整合的功能:它面向全体市场的决策与分别面向各区域市场的决策等价,全社会总剩余最大化目标也可以分解为各区域社会剩余最大化的子目标之和,在其效率较高的情况下,将迫使地方企业改进成本或者退出市场,而只有当地方企业有足够高的效率的时候,全国性国有企业才会选择退出策略。国有企业事实上可以作为一种内部规制工具对市场分割的负面效应进行一定程度的制衡,在明确规制规则的条件下,我们可以通过动态调整企业目标函数以实现整体市场福利的最大化。
