The effects of corporate environmental disclosure on environmental innovation from stakeholder perspectives

Based on legitimacy theory and resource dependence theory, using 111 listed companies among China’s typically high pollution-emitting listed corporations, research into the effects of environmental disclosure on environmental innovation is undertaken. From the perspective of stakeholders, we analyse the moderating effects of different proportions of institutional investor holdings and types of enterprises on the relationship between environmental disclosure and environmental innovation. The results indicate that corporate environmental disclosure has a positive role in promoting environmental innovation; the proportion of institutional investor holdings has a positive moderating effect between environmental disclosure and environmental innovation. However, there is no significant difference between state-owned enterprises and private enterprises in terms of the effect of the environmental disclosure on environmental innovation, which possibly arises because both types of enterprises make full use of their own advantages to instigate environmental innovation through environmental disclosure. The conclusions may help enterprise decision-makers implementing environmental innovation and government policy makers formulating scientific policies to promote the clean production in enterprises.

论行业垄断的成因、危害及治理

竞争是市场经济最基本的机制，也是市场经济活力的源泉。目前，我国正处于经济转型阶段，市场机制不完善，影响、妨碍企业公平竞争的问题还比较严重，其中的一个突出问题就是行业垄断。许多经济学家都认为，中国经济起飞的“拐点”之所以迟迟未能出现，重要因素之一就是制约中

The structure of strategy-proof random social choice functions over product domains and lexicographically separable preferences

We characterize the class of dominant-strategy incentive-compatible (or strategy-proof) random social choice functions in the standard multi-dimensional voting model where voter preferences over the various dimensions (or components) are lexicographically separable. We show that these social choice functions (which we call generalized random dictatorships) are induced by probability distributions on voter sequences of length equal to the number of components. They induce a fixed probability distribution on the product set of voter peaks. The marginal probability distribution over every component is a random dictatorship. Our results generalize the classic random dictatorship result in Gibbard (1977) and the decomposability results for strategy-proof deterministic social choice functions for multi-dimensional models with separable preferences obtained in LeBreton and Sen (1999).     

政府间事权划分思路的比较与综合:基于中国现实的分析

政府间事权划分的传统思路是基于政府是公共产品供给主体这一基本认识,在既定的层级制政府架构下完成公共产品供给事权划分,具体采用了按公共产品种类、受益范围、部门单位隶属关系以及按事权构成要素进行划分的方法,但都难以完全做到在体现公平和效率原则的前提下明晰划分政府间事权.本文基于公共产品多中心供给这一基本认识,引入"功能覆盖型竞争性辖区"理论,把从公共产品的具体性质分析入手,通过设计、选择合适的供给主体来完成公共产品供给事权划分的思路称之为新思路.通过比较,可发现两种思路各有得失.因此,优化政府间事权划分,应实现两种思路的结合,以传统思路为主,新思路为辅.对遵循传统思路难以在层级制政府间明晰划分事权的公共产品,可具体问题具体分析,考虑选择合适的非政府供给主体,实现公共产品的多中心供给,这有助于解决政府间事权划分的棘手难题.     

Drastic innovations and multiplicity of optimal licensing policies

Considering the licensing of a drastic cost-reducing innovation by an outside innovator in an n-firm Cournot oligopoly, we show that when the innovator uses combinations of fees and royalties, there are either n − 1 or n optimal licensing policies.     

A New Approach to Gravity Anomaly Separation: Differential Markov Random Field (DMRF)

In this paper the authors introduce a novel approach to stochastic image processing, denoted as Differential Markov Random Field (DMRF), which has been applied to gravity anomaly separation problems. The advantages of the method are that it introduces only little distortion into the shape of the original image and that it is not affected significantly by factors such as the overlap power spectra of regional and residual fields. Testing of the proposed meth using synthetic examples gave excellent results.     

基于红外通信的数据采集系统

随着红外技术的发展,红外通信已经成为越来越普及的无线通信方式。红外通信是以红外线为载体来传送数据信息,具有操作简单、可靠性高、功耗低、抗干扰能力强、空间接入灵活、无需连接线等优点,所以越来越受到重视。数据采集系统是在多种场合都有着重要应用的系统,现场的某些参数要通过传感器采集后送到前台机的数据接收端进行初步的处理,然后前台机要把这些数据传输给后台机进行更进一步的分析和处理,以便于掌握现场的实际情况并采取进一步的措施。
