However, the impact of informatization on enterprise benefits is all-round, and the factors affecting enterprise benefits are also various. Judging from the benefits of enterprise informatization, we can intuitively see that its main functions are in two aspects: reducing costs and improving efficiency. There are many costs in the process of business operation, including manufacturing costs, sales costs, inventory costs, management costs, research and development costs and so on. For example, through the office automation system, paperless, reduce office costs, labor costs; Reduce product research and development costs through virtual manufacturing and virtual design. Information technology has improved the efficiency of enterprises. The improvement of efficiency is directly reflected in the shortening of unit time to complete the same work. If enterprises shorten the whole cycle from the beginning of supply chain to the sale of products to customers through information technology and accelerate the turnover of related funds, the time value of funds will produce economic benefits for enterprises; The increase of output per unit time will also bring more income and competitive advantages to enterprises, and will also have a good impact on the social image of enterprises. Informatization provides enterprises with advanced tools and management platforms. As long as the enterprise can correctly implement and apply it, it will certainly promote the growth of enterprise benefits. The benefit of enterprise management is the result of using all kinds of resources (including informatization) owned by enterprises. Informatization is not the decisive factor for enterprises to obtain operating benefits, but only one of the promoting factors. We can't simply blame the failure of enterprise management on the implementation of informatization, nor can we blindly invest regardless of the overall benefits of enterprises. In this sense, it is difficult for us to accurately calculate the investment income of enterprise informatization.
