In the era of educational informatization 2.0, the construction of vocational education informatization has shifted from focusing on standardized supply of "things" to meeting diversified needs of "people". Under this background, educational information enterprises participating in vocational education are no longer satisfied with being a single product provider, they have begun to transform into comprehensive services and operational services to meet the personalized, diversified and deep-level educational needs of consumers. The combination of technology and services has become the development trend of educational information enterprises. At present, there are still some problems in the participation of such enterprises in vocational education, such as lack of continuous cooperation, uncertainty of service extension and inconsistent discourse systems. By developing the enterprise's own service supply capability, identifying the dos and don'ts of information-based supply and strengthening the external guarantee of the institutional environment, educational information enterprises are probably able to break through the bottleneck of participation in vocational education, thus promote the new integration of industries and education.
