接著，分三今方向對markowitz模型進行了拓展研究：第一個方向是運用markowitz模型時如何減少計算量，本文利用無風險資產來改進markowitz模型的有效邊界，利用單因子或多因子模型來減少收益率協方差的計算量等等；第二個方向是增加考慮因素，諸如交易費用、資金限制、最小交易單位限制，風險測度和國際組合證券的匯率風險，使markowitz模型更貼近我國的實際；第三個方向是對markowitz模型進行動態拓展研究，提出了將證券收益率看成是隨機序列時的投資決策模型，深入研究了m ? v有效邊界隨資產品種數增加而發生的漂移，並用解析方法和幾何圖形描述了漂移的軌跡和方向。The reason that ec can improve the competitive ability of firms lies in the fact that, the cost of firms can relatively contracted, and the firms have the competitive advantages of enlarging without boundary. the relatively contracting of firms cost means, the effect of diminishing of managerial costs can simultaneously occurred in the fields of production costs, marginal costs, and transaction costs, with the results that the barriers of competition was founded because of the higher transaction costs of provision regarding to the businessmen of productions and services, which are caused by the reduction of production costs rendered by higher productivity, and of managerial costs rendered by the effect of substitution of soft manufactory technology. the relative enlarging of the optimal bound of firms means, that the firms can share managerial costs through the effect of scale of management by the employment of ec, that the scale of firms is enlarged while the managerial costs are cut as a result of the distributing of managerial costs to every liners and proceeds of the firms, which means that the same managerial costs can be used by larger - scaled firms
電子商務之所以能提高企業競爭力，是因為企業成本相對收縮和企業的無邊界擴張競爭優勢，所謂企業成本相對收縮即邊際成本遞減，這種邊際成本遞減效應可以同時出現在生產成本、管理成本和交易成本三個領域中，電子商務通過提高勞動生產率來降低生產成本，柔性製造技術的替代效應降低了庫存管理成本，與此同時，電子商務減少企業與消費者之間的環節，縮短路徑距離而降低企業內外的交易成本，提高了企業產品和服務分銷商改變供貨方式的交易成本，使之形成企業競爭的壁壘；所謂企業最優邊界的相對擴張，是指由於規模管理效應即電子商務運用信息技術使企業以低信息成本共享管理成本，使企業總體管理成本分攤到各個管理環節和流程中，企業規模擴大而邊際管理成本逐漸下降，相同的管理成本可用於管理更大規模的企業，即隨著電子商務在企業中的應用，企業的最優邊界相對擴張了。After china joined wto, with the decrease in the tariff level and with the cancellation of non - tariff rampart, this contradiction will become even more protruding. thus it has been a consensus to reform the current vat and this problem has aroused much attention from the government. at the end of october 2003, our central government put forward " several proposals on implementing the strategies for rejuvenating the old industrial foundations in the northeast china " and also put forward " carrying out the reform of transforming the productive vat into the consuming vat preferentially in the northeast "
