The heterogeneous relationship between board social ties and corporate environmental responsibility in an emerging economy

Firms in emerging economies are faced with multiple, incompatible institutional forces in their environmental activities. Which of these forces will be dominant and instantiated within an organization is partly determined by the social relationships that a firm maintains with external actors. This paper investigates the relationship between board social ties and the level of environmental responsibility undertaken by firms in China, an emerging economy, by categorizing board social ties into three types in terms of the three isomorphic forces in the institutional field (coercive, normative and mimetic). Drawing on institutional and agency theories, using a sample of listed firms in environmentally sensitive industries, and a generalized least squares regression method, the results provide empirical evidence that ties that are linked to coercive and normative forces (i.e., political organizations and universities) are related to a higher level of environmental responsibility; however, those that are linked to mimetic forces (i.e., industrial peers) have a negative association with environmental responsibility, which is mitigated by CEO power. These findings suggest that the heterogeneous effects of board social ties on environmental responsibilities experienced by firms in a context of environmentalism are at an early stage.     

农户小额信贷满意度研究——基于陕西、甘肃农户调查问卷的分析

本文利用Liker五级量表对陕西、甘肃162户农户小额信贷满意度及其影响因素作了调查研究.研究结果表明,农户对农村信用合作社小额信贷业务整体上比较满意,小额信贷已经成为农户重要的筹资渠道.具体来看,农户对于信用等级的评定、还款方式、小额信贷的作用等表示满意,但对贷款授信额度、偿还期限设计、贷款手续、利率和贷款的可获得性等方面不太满意.     

基于全寿命周期分析的电力设备费用模型

针对我国供电企业的实际情况,将电力设备费用分为一次投资费用和运行维护费用两部分,建立了电力设备全寿命周期费用定量模型。针对一次投资费用的特点,建立了基于时间分摊的一次投资费用模型;针对运行维护费用长期发生的特点,建立了基于灰色关联度确定分布类型的运行维护费用模型。同时,将两个费用模型综合考虑,建立了供电企业电力设备全寿命周期费用模型,据此可计算电力设备全寿命周期最小费用和最佳使用寿命。最后,以某变电站综合自动化项目为例,验证了该模型的有效性。

自适应并行遗传算法求解非对称性旅行商问题

遗传算法是一种模拟生物进化的搜索最优解算法.根据交叉概率与变异概率在不同时期的不同要求,提出一个随进化代数和群体的适应度进行自适应调整的策略.同时,采用粗粒度并行策略,使算法具有更好的收敛性、稳定性、更快的速度和更好的优化质量.最后通过一些精典的非对称性旅行商问题对该算法进行了检验,结果表明自适应并行遗传算法可以有效提高遗传算法的求解性能.

CHANGE for a New Economic Structure？

Opportunity in the financial crisis？
For a long time, China＇s fast economic growth is heavily dependent on growth of exports, particularly dependent on exports of low value-added, low technological products. Although the policy-makers and scholars are aware of the importance and necessity of industrial structure improvements since 1992, it is hard to have a real incentive to promote economic restructuring under rapid economic growth.

机制砂的性能及其对混凝土性能的影响

以往对混凝土的研究,土木工作者把更多的注意力放在了水泥、水灰比、外加剂以及粉煤灰和硅灰等外掺材料上。集料也是混凝土的重要组成部分,在混凝土中占有很重要的地位。随着土木建设的日趋发展和完善,天然砂日益紧缺,我们应重新审视集料对混凝土性能的影响。本文就着手研究用机制砂取代河砂对混凝土性能的影响。
