The Chinese government promotes cooperation between colleges and companies in vocational education to improve the supply of skilled workers and increase labour productivity. This study employs the concept of positive coordination – negotiations concurrently addressing productive and distributive questions – to analyse the advantages and limitations of voluntary cooperation embedded in networks. In terms of production, many projects focus on updating, narrowing and deepening curricula to lower the costs of initial training borne by companies and the risk of labour turnover. In terms of distribution, however, the deep and narrow curricula are at odds with students’ preference for general and transferable skills; and the mutual commitments of both companies and students are uncertain. The solutions provided by cooperation are partial and unstable. Overall, they reduce skill mismatches but cannot control turnover or overcome market failure, which undermines tertiary vocational education's contribution to labour productivity.
