This paper attempts to consider and solve the problem for companies to choose the optimal strategic route of green transformation technology investment based on economic fluctuation and their own situation.We apply a real option to conduct scenario analysis on the forecast economic development status and technology and get the optimal investment rules and the optimal choice route of the green transformation technology.The main results are:1) the initial role of carbon trading price is to promote the green transformation of high-energy enterprises;2) enterprise's financial strength is an another important factor that influences green transition success and route selection for enterprise;3) the key factors which influence green transition success and route selection for enterprise are the degree of economic prosperity,the height of the investment of the discount rate,and the development level of the green transformation technology.Furthermore,our theoretical model implicates that government should control the stability and prosperity of the economic environment and provide a good carbon trading mechanism and encourage to cultivate high green transformation technology with the high discount rate investment.
