Today, under the background the ecological civilization construction, many scholars are focusing on the issue of how to keep the balance of the economical, social, political and cultural development and try to make all of them in a sustainable development way. In this paper, we put forward the concept of ecological accountable government. On the analysis of the responsibility system of an ecological accountable government, we try to construct the ecological accountable government in the contract way. Then, we consider that the ecological accountable government’s contract system was composed of three contract levels, which including the moral contract, the political contract and the executive contract. All these three levels of contract have different functions and definitions, but their goals are the same, which is to try to make the government fulfill its ecological responsibility. Finally, we talk about the constructional thoughts which including six different dimensions, such as the administrative value’s construction, the theory basis of the political ethics and some relevant background system settings, the subject of responsibility, the responsible receptors, the content of responsibility, and the responsible mechanisms.
