Abstract:From the perspective of system, based on literature method and expert survey method, a two-dimensional transformation and upgrading system matrix of supervision enterprises is constructed with project management and technology subsystem as horizontal, and each stage of project investment decision, construction implementation, operation and maintenance as vertical, and the entropy weight method is combined with the degree of cooperation to quantitatively analyze the degree of cooperation between the transformation and upgrading system of supervision enterprises and each stage of the project life cycle. Identify the key subsystems affecting the transformation and upgrading of supervision enterprises in each stage of the project life cycle, and put forward suggestions accordingly, in order to provide references for promoting the transformation of the whole process of engineering consulting business of supervision enterprises.
