As an innovative lever of industry-education integration policy,the city-region industry-education alliance,despite a series of policies providing detailed paths to follow,still faces challenges in the actual construction process.These challenges include non-standardized evaluation mechanisms for the development of"dual-teacher"teachers,inadequate design of multi-participation mechanisms,identity crisis in the 1+X certificate system,and multiple institutional logic conflicts within the modern apprenticeship field.These issues have led to a significant gap between the expected goals-a good ecological environment of"sufficient institutional supply,strong guarantee of conditions,and deep integration of industry and education"-and the reality,with one of the key reasons for the divergence between reality and ideals being the lack of comprehensive institutional support.The city-region industry-education alliance aims to leverage high-quality resources from various regions and fields in industrial parks to create a new community of multiple stakeholders for mutual benefit,requiring a solid institutional foundation.Therefore,it is essential to explore the strategies for institutional construction in the development of city-region industry-education alliances from an institutionalism perspective.Firstly,it is necessary to enforce standardized evaluation and recognition policies for"dual-teacher"teachers and create a multi-participation teacher training mechanism.Secondly,improve the quality assurance mechanism for the X certificate system to enhance social acceptance.Thirdly,coordinate the interests of various stakeholders within the modern apprenticeship field to resolve multiple institutional logic conflicts.Finally,clarify the ownership of vocational colleges as a key step and carry out mixed-ownership reforms.
