摘要：
To protect environment need manufacturers to improve pollution abatement technology, and technology adoption is the effective means for achieving the purpose. Using real option theory and dynamic program method, this paper focuses on the research of the optimal timing of firms to adopt new pollution abatement technology under tradable emissions permits. It is assumed that in the process of new pollution abatement adoption, the manufacturers face two kinds of uncertain factors that are the speed new technology appearing and new technology innovation level. The results show that the optimal adopting timing of firms adopt new pollution abatement technology interrelate with many factors, this factors include new technology appearing speed, technology innovation level, discount rate, initial pollution abatement technology, efficiency of production technology, emissions permits price, product price, and output elasticity, etc. And it is showed by simulation model that the faster new technology appearing the earlier manufacturers adopt new technology and the higher the new technology improve the efficiency the later manufacturers adopt new technology. On other variables, we also obtain the corresponding simulation results.

摘要：
It is very important for firms who pursue profit maximization whether and when to carry on pollution abatement technology investment under tradable emissions permits and uncertainty. To consider an irreversible pollution abatement technology investment projects under a winner- takes-all patent system and the uncertainty takes two distinct forms: the technological success of the project is probabilistic, while the economic value to be won evolves stochastically over time. Considering these effects of uncertainty and using real options theory, it's to present a pollution abatement technology investment strategy option gambling model, and by analysis this model to give the best opportunity of manufacturers to carry on pollution abatement technology investment. The study shows that in pollution abatement technology investment, the pre-emptive effect damages option values to a significant degree, causing investment to take place sooner than in either the single-firm or the coordinated case.
