A Study Of Enterprise Project Investment Decision Model Construction And Applications In The Background Of Low Carbon Economy

In the context of growing problems like global warming, energy shortage, environmentalpollution and so on, low carbon economy, as a green economy development mode, draws more andmore attention. How to adapt to the requirements of low carbon economy has become an importantresearch subject for each country and enterprise to face. The paper attempts to construct an investmentdecision-making evaluate index system and model of enterprise projects in the background of lowcarbon economy, on the basis of low carbon economy theory and investment decision-making theory,to help enterprises to carry on a reasonable and scientific investment decision-making in the age oflow carbon economy.The paper firstly determines the research direction through making a systematic arrangement andanalysis of research findings about low carbon economy and investment decision-making at home andabroad, and points out the deficiency in the relevant research. Then, the paper expounds low carboneconomy theory and investment decision-making theory. The paper constructs the investmentdecision-making evaluate index system in the background of low carbon economy with DelphiMethod. There are three dimensions including low carbon environment factors, financial benefitfactors and social impact factors in the system, which have ten specific indexes including energyutilization rate, comprehensive energy consumption per unit output, greenhouse gas emission, zerocarbon energy proportion, net present value, investment recovery period, internal rate of return, rate ofreturn on investment, environmental protection investment proportion and employment benefits. Inthe process of model construction, the paper mainly adopts Analytic Hierarchy Process and Techniquefor Order Preference by Similarity to Ideal Solution, and improves the combinatorial weightingmethod to calculate weight determination. In the final part, the paper undertakes a case study with theconstructed decision-making model, validates the effect of the model, and offers a proposal to Acompany of the case in the parts of concepts and methods of project investment decision.The study show that traditional investment decision methods with the view of financial benefitscan not adapt to the requirement of low carbon economy. Enterprises should actively respond to lowcarbon economy influences to the investment decision, and adjust the mode of production and theinvestment method so that enterprises can better develop in the age of low carbon economy.
