BCG Matrix’s Problems and Its Reconstruction ZHOU Zhenping, ZUO Zhanping Hebei University of Economics and Business, Shijiazhuang, China, 050061 zzhenp_511@126.com Abstract: Boston Consulting Group (BCG) Matrix is a common approach to managing a portfolio of different strategic business units (SBUs) or major product lines.
