The purpose of this paper is to make clear the actual state of management strategy, specifically, whether or not the management strategy is well functioned in terms of long term profitability, with regard to the companies which belong to the strategic groups in the construction industry of Japan consisting of the general contractors, EPC contractors and residential housing constructors after 2000s. The research is mainly focused on the general contractors. The 49 listed companies with the sales amount of more than 100 billion yen are selected in the construction industry and the sales amount and ROS of these companies over the past 40 year were researched every strategic group (the general contractor group, EPC contractor group and residential housing contractor group) in order to know whether the management strategy of each company was well functioned or not. No companies in the general contractor group, two companies in EPC contractor group and one company in residential housing constructor group are found to well function with regard to the management strategy as far as the analysis of sales amount and ROS is concerned this time. Some strategic actions to the general contractors by the stake holders observed after 2000 up to now are explained to some extent by use of the result of this research.
