The Study Of Contribute Rate Of Safety Investments To Economic Growth And Safety Investments Decision-Making

To make the government and enterprises realize safety investments' effect and to assess it, a model is built up in this paper to calculate the contribution rate of safety investments to economic growth. The contribution rate of safety investments to economy growth in 2002 deduced from this model is about 3.14%, which proves that safety investments are also productivity in theory and practice data.To avoid the defects of loss calculation methods, this paper proposes to sort the loss subject into small ones in a scientific and authoritative way. In view of the problem that our country's casualty compensation standard is not unified and varies form town to country, this paper builds up a model to calculate the human life value. It points out that human's life value is not different because of his/her identity and social station and life value is not all the same .The value is varied from one to another but it's based on the rule "all men are equal in the eyes of law". The model raises up human's life value, which has minimum, no maximum. It is useful in loss calculation and rising up the compensation standards. The life value of a 35-year-old Chinese man, whose monthly wage is about 1100 yuan, is over 540000 yuan deduced from this model based on the GDP of China in 2005.The life value of a 35-year-old American man, whose monthly wage is about 3500$, is about 1.75 million dollars based on the GDP of America in 2005, which accords with the actual compensation standard(1.6 to 3 million dollars) of America. These data prove that the model is suitable for the economy level of our nationality. The problem rising up because of the higher human life value is also discussed in this paper.The model of yield function, safety investment cost function and safety functions are given out in the study of safety investments decision-making. The capability of decision-maker and scientific decision-making procedures are also introduced in this part. The accident loss is predicated with the Verhulst model of Grey system theory and the most-benefit-point and its calculation method are introduced, which makes the scientific decision-making have warrant.The cultivation of safety consciousness and building up safety culture are basic projects and two of the most important ways to improve the severe situation of safety production. Building up the "people oriented " security view, leader's recognition, all the people participation, ruling the security training, building up security burden share rule are steps of how to build up safety culture.
