In order to motivate the implementation and promotion of the whole-process engineering consulting mode in my country's construction industry,and accelerate the transfor- mation and upgrading of the engineering consulting industry,based on the research of relevant national policies and literature results,combined with field research data,from four dimensions of policy norms,industry markets,consulting enterprises and industry personnel, 16 factors which affected the promotion of the whole-process engineering consulting mode were systematically summarized.The integrated model of decision making trial and evaluation laboratory(DEMATEL)coupling with interpretative structural modeling method(ISM) was used to analyze the types and the causal influence degree of influencing factors,and construct acomprehensive hierarchical structure diagram of the factors that affected the promotion of the whole-process engineering consulting mode.There search results show that insufficient policy support and scarcity of inter disciplinary talents areessential causes, unclear user needs,insufficient maturity of new consulting modes,and insufficientability of enterprises to provide integrated consulting services are transitional causes,uncertainty of entrustment ways,service types and scope,imperfect contract templates and technical standards,unclear consulting service remuneration calculation methods,and lack of consulting process supervision and result evaluation systems are surface causes.Finally,based on the research results,relevant suggestions for the promotion of the whole-process engi- neering consulting mode are put forward to provide references for accelerating the application of the whole-process engineering consulting mode in the construction industry to carry out engineering consulting services.
