Nationwide unification of carbon emission right market in China has long been proposed yet not achieved. Launching of the nationwide trading center at Shanghai was a recent great step towards this target but the regional pilots covering respective zones are still in operation. With all trading data in those markets from their inceptions, this paper investigates the development status and trend of each submarket, based on which, it is revealed that sudden replacement of regional markets by the unified nationwide trading center is infeasible at the present stage, furthermore, feasibility of market merging is analyzed and optimized route for essential unification is designed. This paper contributes to deconstruct the value of carbon emission right and interprets its properties of option value, the equivalence of which value from the perspective of financial investment and enterprise operations is explored and formally established. Applying the geometric Brownian motion and optimal stopping time to model the carbon asset operation, option value of carbon emission right is estimated and marginal return-ability of its consumption is calculated for each region. Based on the analysis regionally, market merging is simulated and optimized route for nationwide market unification is proposed with policy suggestions.
