城乡医疗卫生资源均衡配置问题探析——以广州市地方政府投资为例

卫生资源配置不平衡,城乡之间差异较大,一直是我国卫生事业发展中的突出问题。城市与乡村无论在医疗卫生经费的投入、卫生机构的建设、技术人员的培养还是医疗保障的建设之间存在较大差距,因此城乡医疗卫生资源统筹发展至今还是我国卫生事业领域改革的重点。本文对广州市地方政府对城乡医疗卫生资源的投资作为分析基点,通过对城乡医疗卫生资源投资额度等数据的分析得出医疗卫生资源配置现状,并在此基础上分析其存在问题的原因,提出一些可参考性的对策建议。

基于子集模拟的建设工程项目多资源均衡优化算法

为高效、稳定地求解建设工程项目管理过程中的多资源均衡问题,提出一种基于子集模拟的优化算法.多资源均衡问题中,如直接采用工序计划开始时间作为决策变量,在优化算法的实现时易违反工序间的逻辑关系.为避免该问题,本文采用工序计划开始时间的间隔率变量表示(在二者的映射中考虑工序间的逻辑关系),并据此建立间隔率变量表示的建设工程项目多资源均衡优化模型,以简化基于子集模拟的优化算法的操作流程.通过算例验证,与目前应用较广的遗传算法相比,本文提出的优化算法在最优解的获取稳定性上有较大改进.

Research on Motivation of Corporate Social Responsibility Based on Game Theory

The negative externalities of businesses brought serious social and environmental problems. Based on externality theory and game theory, the author in-depth analyzes intrinsic motivation of corporate social responsibility, and points out that corporate social responsibility will increase production costs, so companies will not take the initiative to raise the level of social responsibility. Through the analysis of corporate social responsibility profits, the paper reveals that if the government lack reasonable system to regulate corporate behavior, then the In＇m, pursuiting maximizing profit, will choose the Nash equilibrium ofconsumpting public resources, and not take the initiative to fulfill their social responsibility to seek the Pareto equilibrium of the whole regional optimal, which results in high output and low returns. The research finds that the government should strengthen the publicity of corporate social responsibility, privatization of corporate social responsibility benefits and establishment of corporate social responsibility system and other means to guide and standardize the corporate social responsihility.
