Companies that not only abide by environmental regulations, but also discover new techniques and adopt newmanagement methods to reduce negative environmental impacts often have positive effects on corporate profitability. Inorder to meet the needs of sustainability of enterprises and protect environment, the concept of green management isdeveloped and regarded as an important direction of management theory of the 21st century. Though there are manytheories and practices about green management in western countries, they are built based on the developed marketeconomy, which are not suitable for Chinese enterprises absolutely. By analyzing the viewpoints and models of theoverseas and domestic experts and scholars, combining characteristic of China's market economy, this paper points outthe real connotation of enterprise green management - the combination of ecological harmony (harmony between humanand nature) with human harmony (harmony among people), establishes a 3D theoretical model, points out the defects ofenterprise's green management in China, reanalyzes and redesigned enterprise green management, which paves the wayfor the deeper and broader development of green management.  相似文献

This paper points out that one of the main reasons for income gap between urban and rural areas in china is difference of human capital reserve on education which are decided by Chinese government's urban area privileged policy and the current education system. This paper also compares the different human capital reserve in two area, and analyzes the under-qualified human capital reserve in rural areas is resulted by these following reasons: The shortage of public spending in compulsory education for several decades has contributed to low school attendance and the great illiteracy beyond urban areas; the inefficient educational system has caused peasants to lose interest in education; No support for adult education has closed the doors for adults to earn money in non-agricultural industries. Vocational schools cannot attract the huge number of potential customers since their curricula and skills are out of date. As policy suggestions, governments should invest enough money in compulsory rural education, and creating a pragmatic rural education system is also vital.  相似文献

Based on the assumptions of "information transfer" and "information creation", this paper educes the multiplied growth mechanism of network information: that the gross quantity of network information (Im) is about n times as much as the quantity of real network information (Ir). According to this theoretical model, we give a uniform explanation to all kinds of information growth models in existence, and put forward some proposals, such as "forbidding information transfer" and "building up the central information base", to control the repeated information flooding on the network and facilitate the full use of network information.  相似文献

为解决供应链管理环境下军用物资采购多供应商选择问题,建立了以供应综合成本最低为目标函数,满足多个约束条件的组合优化模型。为解决求解的困难,采用变换分解算法,将原模型转换为整数规划问题。根据不同迭代方式,给出了两种基本运算步骤。算例分析表明:该新方法克服了常规供应商选择评价方法只针对单一物资供应过程和面向单一供应商选择过程的局限性。  相似文献
