This paper discusses whether target costing (TC) is affected by the impacts of external circumstances and appears dynamic in real estate development industry. A case study was conducted and combined with literature reviews to test this proposition. The results of this paper show that the formula appears dynamic on the impacts of economic depression/recession, inflation, and change of governmental policy to assist the firms in the achievement of planned profits. TC, as a strategic profit management system in the industry, exhibits brisk utilization in a dynamic formula with more of a focus on value added to maintain fixed profits. It is different from the focus on cost reduction by a static formula in previous literatures. 展开更多
