Abstract:The 18 th National Congress of the CPC manifeste dt he ecological civilization construction strategy of the Party which put the ecological construction as an initial proposition for the whole country, equaling economic construction, political construction, cultural construction and social construction. To be aware of the essential role of ecological construction, Chinese academic circle and political leaders experience a long and bumpy road. From unknown to known, they gradually construct their systematic consensus both from science and public policy approaches. On a philosophical sight, it is also a progress from the realm of necessity to the realm of freedom. To straight out the whole progress of consensus, the contributions from academic research are hard to be neglected, including the great effort on producing the knowledge of ecological protection and developing the policy study at the same time. Making the scientific consensus become policy–making consensus strongly depends on the wisdom of scientist to feed their research into the policy-making process. Ensuring the green development of China in the future, the brain of scientist and the brain of policy maker have to learn to work together. The academic scholars should enhance their capacity in policy consulting while the policy maker should learn how to listen to these suggestions. The institutionalized cooperation of two brains will construct the true “civilization” of the society.
