【正文】 rategy is too mechanical and single, in fact thin dog product strategy can be multiplechoice feasibility.In 2, General Electric Matrix Model Applicability Comparison AnalysisView of the Boston matrix model of the defect, the United States of America General Electric Company for its optimization and improvement, with the petition status and industry attractiveness of these two more prehensive index replacement the original thin index, and the index value dichotomy is improved for more precise three points, to form the nine quadrants of the new model the industry attraction / enterprise strength model, namely the general electric matrix model (GE Matrix), also known as the strategic business planning grid (Strategic Business Planning), for managers to make the product portfolio strategy provides more reasonable analysis decision making tools, and emphasizes the introduction of time variable to make time series atlas for parison, enhanced the feasibility of strategic choice, thus greatly enhance the scope of application of the its limitations is integrated advantage index derived from trivial calculation the negative effect, making it two to define the values of indicators will be highly subjective judgment of ponents, thus the evaluation and analysis there is a fuzzy, reduces the model of scientific contrast, Boston matrix model two index has a clear the more conservative approach is to foster strengths and circumvent weaknesses, the Boston matrix model for the analysis of petition, and the general electric matrix model for the enterprise resource allocation analysis.In 3, Hoffer Matrix Model Applicability Comparison AnalysisIn order to enhance matrix applicability, people are constantly on the model improvement and optimization, which are more representative of the model is C Hoffer matrix (C Hofer Matrix) and threedimensional analysis diagram product / market evolution matrix (Product/market Evolution Matrix) extends the above two kinds of product strategy selection method, with the product / market development of five stage index replaces the business growth and industry attractiveness of two indicators as ordinate and abscissa, original petitive position three index value formation as many as fifteen quadrants of the new matrix, and for each quadrant of the product configuration of different strategies of prescription, thus constructs of most enterprise matrix must be one or the other of the three kinds of typical product portfolio matrix: growth, profitability and balance types of product portfolio matrix problems, pany overall strategy will have different choices.4, a threedimensional diagram analysis of Applicability Comparison AnalysisThree dimensional analysis diagram method for dimensional extension of Boston new addition rate of profit index dimension, coordinates in the threedimensional space, with X, y, Z three coordinate axes represent the market share, sales growth and profit rate, each coordinate axis and for high, low two segments, so that you can have eight possible is also a kind of used to analyze product portfolio is sound, important balance in the rate of profit index model of reality into increased profitability description ability, improve product strategy choice of financial of Boston matrix in the presence of sales growth and market share of two indicators represent weak still did not overe the defects.In 5, matrix model for overall analysisThe selection of product strategy model are called business portfolio analysis method (Portfolio Analysis).Their mon scope firstly is the existence of product portfolio rather than a single product status, role is for each product to find out the most suitable management strategy, the pany overall product portfolio strategy is decisionmaking it does not apply to specialization management or business is relatively simple in small and medium sized enterprises.Secondly, as a result of market demand and petition situation, product portfolio for each item, inevitably in the changing market environment , enterprises need to frequently on product portfolio of each project are analyzed, according to the market environment and resource changes, timely increase should develop products and eliminated should withdraw from the product, thus forming the enterprise can obtain the maximum profit of the optimal product mix, to achieve the dynamic balance of product is in fact the product portfolio dynamic optimization problem, the only way is through the continuous development of new products and remove decay products to the choice of the optimal product mix should consider the following two groups of factors: a product mix of each item or product line market share, sales growth and profit rate, analysis of various factors will be changed, and these changes to the enterprise profit is the enterprise resource condition and market environment, market environment changes rapidly and very plex, each enterprise resource is limited, therefore, must consider the two factors, according to may, timely adjustment of product the two factors that are mon in the product bination decision matrix model important indicator the two factors information acquisition of large amount of difficulty big, the solution is to strengthen the construction of enterprise information system and strengthening the consciousness of the information management, two are familiar with and understand the model index meaning and calculation method, if lack of information to select other synonymous information to replace, and error adjustment.Again, choose the best product bination is the key to enterprise39。s each product or product line to make a correct evaluation, determine its market position, but for a product or product line of many enterprises is a very plicated problem, and the business portfolio analysis is a useful strategy analysis and dynamic balance management product portfolio provide a framework, which helps
