振兴东北老工业基地必须建立良好的市场环境

振兴东北老工业基地,打破地方保护。建立统一、开放的市场。是促进经济发展的必然选择。但目前东北三省的市场环境仍然不够开放,起码与经济发展的要求相差甚远。为了防止在振兴老工业基地过程中地方保护主义作怪,东北地区上上下下都要树立更加开放的观念,从长远的目标出发。建立统一、开放的市场。     

我国环渤海地区人口流动与社会经济的协调发展

流动人口与区域经济社会协调发展成为当前我国流动人口管理的重要问题。在经济快速发展和流动人口规模持续增长的过程中,环渤海地区正面临着流动人口如何与经济社会发展相协调的严峻挑战,因而在＂十二五＂时期应该通过深化城乡体制改革、加快产业结构调整等措施,积极促进流动人口更好地服务于区域经济社会发展。

Differential evolution utilizing a handful top superior individuals with bionic bi-population structure for the enhancement of optimization performance

ABSTRACT

In this paper, we propose a new DE variant incorporating a new mutation strategy and a bionic bi-population structure to enhance the overall performance of the canonical DE algorithm. As it is known to all that the guidance of a handful top superior elites is usually better than the guidance of only one elite in many cases, therefore, a handful top superior individuals are employed in the newly proposed mutation strategy for individual evolution. Moreover, hybridization of two populations of a certain species can improve the adaptation to the environment, and business and information exchanges between tribes can help their economical and technological development, so a bionic bi-population structure is also employed in the new DE variant for information exchanges. Both of the two aspects make the new algorithm achieve an overall better performance, and experiment results show that a handful top superior individuals with bionic bi-population structure has better performances on optimization accuracy, convergence speed and success rate under these tested benchmark functions especially those other algorithms may be trapped into local optima.     

论积极财政政策下的税收政策调整

以发行国债增加政府支出和事实上增税的财政政策，不是完整的积极财政政策，这是我国仍处于通货紧缩局面的重要原因。积极财政政策应该两条腿走路，即在增支的同时，进行减税。但由于各种客观原因，大规模减税的条件还不具备，只能实行结构性减税，以促进投资、消费、出口的增长，尽快走出通货紧缩的不利局面。     

试论环境会计与企业发展

进入80年代,环境问题由地区性问题上升为全球性问题,会计与环境破坏有重大牵连,对会计责任的要求已经超出了人际和契约关系的范围,拓展到了社会关系的层面。会计工作是企业存在和发展的基础和前提,而建立并实行环境会计制度是企业实现可持续发展的必要保证。环境会计的实质是要将企业在生产过程中所造成的牺牲环境质量的代价。随着社会经济的发展,会计与环境的联系会越来越强,用会计处理一些环境问题必然会成为当代和未来会计学发展的一大趋势。     

Making the right friends: A social network perspective on newcomer socialization in teams

Despite the prevalence of work teams in organizations, how newcomers become integrated into teams remains an understudied area. Drawing on research related to indirect social resources, in this paper we employ a social network perspective to examine how close teammates' friendship centrality can facilitate newcomers' adjustment by fostering the newcomers' own social capital in teams and promoting their subsequent task performance. Furthermore, our model incorporates institutionalized socialization tactics and political skill as two contingencies that can further strengthen the positive effects of indirect social resources on newcomers' adjustment. In a time-lagged study using multiple sources of data, we found good support for our hypotheses. Specifically, close teammates' friendship centrality was positively related to newcomers' task performance through the mediating effect of newcomers' own friendship centrality in teams. The two moderators further strengthened this indirect effect. Overall, this study highlights the importance of “making the right friends” to facilitate newcomer adjustment into teams.

Can voluntary environmental regulation promote corporate technological innovation?

The impact of environmental regulation on technological innovation has been widely discussed in the academic circle. Based on the panel data of 403 Chinese manufacturing firms from 2010 to 2015, this paper explored the role of voluntary environmental regulation in technological innovation. The results showed the following: First, both voluntary environmental information disclosure and environmental management system certification had a positive effect on corporate innovation investment. Second, compared with the impact of environmental information disclosure, the impact of environmental management system certification on corporate innovation investment was more significant. Third, there was a significant positive interaction between environmental information disclosure and environmental management system certification. Finally, the effect of voluntary environmental regulation on corporate technological innovation in heavily polluting industries was stronger than that in lightly polluting industries.
