The electric door industry has emerged along with the development of the architectural decoration industry.

With the rapid development of industries such as architectural decoration and the gradual improvement of people's requirements for architectural decoration, intelligent building materials have emerged.With the rapid development of industries such as architectural decoration and the gradual improvement of people's requirements for architectural decoration, intelligent building materials have emerged. Electric doors, as high-tech products that pursue environmental protection and energy conservation as well as convenience and comfort, have gained popularity among the public with their elegant and generous appearance and spacious open facades.

From the statistical analysis of the financing sources of electric door enterprises, it can be seen that the main sources of funds for electric door enterprises are still owner's equity, retained earnings and informal equity. Therefore, it is not surprising that electric door enterprises turn to private capital, commercial credit and informal credit to finance their electric door businesses. The ideal financing method for electric door enterprises in the market economy should at least meet three conditions: the funding supply entities have a natural advantage over traditional financial institutions, can obtain higher returns, and therefore are willing to take on greater risks; the funding supply entities can provide convenience for electric door enterprises in financing while also bringing management assistance to them; the funding supply entities can overcome the disadvantage of high costs in electric door enterprises' financing. In the current financing methods of electric door enterprises in China, the degree of satisfaction with these three conditions is not satisfactory. Therefore, we should explore the improvement and innovation of electric door enterprise financing methods based on the objective requirements that are conducive to the dispersion and resolution of risks for electric door enterprises, conducive to obtaining various value-added services and assistance, and conducive to reducing the financing costs of electric door enterprises.

Electric door enterprises are the most dynamic economic organizations in China's economic development. However, this economic role is not well-matched with their position in the overall social resource allocation. This mismatch is reflected not only in the unreasonable financing structure of electric door enterprises themselves, but also in the narrow channels, scarce sources and single methods of obtaining funds for electric door enterprises. The traditional financing methods for electric door enterprises not only cannot change the situation of narrow financing channels and scarce sources of funds for electric door enterprises, but also exacerbate the contradiction that the effective capital demand of electric door enterprises cannot be guaranteed by reliable sources of funds, alienating the financing structure of electric door enterprises and affecting their business performance, and directly reducing the functional role of the capital market in supporting the development of electric door enterprises. The problem of unreasonable financing structure and single financing methods for electric door enterprises has become a focus of transforming the growth model and adjusting the industrial structure. In fact, it is also a challenge faced by the capital market system arrangement and financial market resource allocation in China. In this regard, the rapid development of the electric rolling shutter door industry in 2009 allows us to study the capital market system from the perspective of supporting electric door enterprises, innovate the financing methods of electric door enterprises, and promote the common development of the capital market and electric door enterprises.
