Abstract:Reasonable profit distribution among enterprises in ecological industrial park is one of the most important channels of inspiring enterprises to adopt cooperation behavior and promoting sustained and stable development of ecological industrial park. This paper establishes improved shapely model of profit distribution among enterprises in ecological industrial park, sets ecological innovation ability, risk factors and input resources as correction factors, uses DEMATEL model to empirically determine key correction factors, uses AHP method to determine weights of three correction factors, uses ideal point distance based on Zadeh, ideal point deviation weighting and hamming distance to determine the correction coefficients of improved shapley model. Finally this paper demonstrates feasibility and operability of profit distribution among enterprises in ecological industrial park based on improved shapely model through form of examples.
