Strategic Choices of General Contractors in the Context of China's Industry Chain of Construction Industrialization

Amidst the challenges of economic downturn and construction industrialization, the profits obtained by general contractors through comparative advantage strategies are slowly decreasing, and thus, new strategic choices are required. The collaborative division of labor effect in the industry chain can improve profits and labor productivity, which is an important driving force for enterprise transformation and development. Therefore, a need arises to improve the profits of general contractors in the industrial chain system composed of prefabricated component suppliers, general contractors, and building development enterprises. Accordingly, this paper constructs a backward integration, forward integration, and bidirectional integration Stackelberg game model based on the proportion of resource investments, with general contractors as the main decision-making body. It then compares and analyzes the optimal decision-making values in different situations to study the optimal strategic decision-making problem of general contractors. Research results indicate the following. (1) All three integrated strategies can improve the profits of general contractors. When the proportion of resource investment meets certain conditions, the profits of general contractors under the bidirectional integration strategy are the highest, while the sustainable performance of the industrial chain and prefabricated buildings can be increased and the coordination of the industrial chain can be achieved. Thus, it is the best choice for a general contractor. (2) As a prefabricated component supplier needs to carry out continuous technological innovation activity to obtain a cumulative effect, the return on investment of forward integration is less than that of backward integration. (3) General contractors may consider choosing to carry out bidirectional integration strategies of forward integration followed by backward integration.
