With the help of modern systematic analysis method, the efficacy of safety incentive mechanisms is discussed in detail. The research shows that more effective avenue to reduce accident is to differently use motivation measures in practice.展开更多

How to effectively motivate such people create greater wealth for the enterprise has become the key problem of the era of knowledge economy. Based on the concept and characteristics of knowledge workers, this paper uses classical analysis framework of incentive theory; through quantitative and qualitative analysis, it points out the existing problems and puts forward solutions on the basis of full analysis of the present incentive situation.展开更多
