Development of efficient methods to accurately estimate the company value requires assessing the conditions of the external and internal environment of the company. We consider the specific application environment for the products of each RFID company, for example, in the financial system, real estate, logistics, retail, product traceability, vehicle, railway, software system and other industries. Since downstream company usually purchases the large majority of its needs from the upstream company, downstream industry boom index is adopted to descript the demand scale of the downstream companies. The other external environment factors include domestic economic growth, inflation, and interest rate. And the factors depicting the internal conditions of the company consist of financial indicators which describe company's health survival and development capacity, company operation indicators that characterize business operating capacity, profitability indicators that represent the corporation profitability, and development capacity indicators that depict company potential ability for expanding scale and growing strength. The factor hierarchy structure shown in Fig 2 illustrates key factors which are said to impact on the company future profit growth. A total number of 29 indicators are considered, and all these 29 indicators can be further grouped into 8 dimensions. Once the key factors affected the profit are identified, we develop the value evaluation model which integrates these factors into a cause-effect framework, as shown in the following sections.
