The change in the policy of industrial land renewal in many mega-cities is the result of a game between government and market.The principle of government policy-making is to balance its long-term benefits (tax revenue) and short-term benefits (land revenue).The policy of industrial land renewal is made to achieve this balance.And the renewal policy is gradually improved in terms of spatial indicators,self-ownership proportion,holding periods,and land management.And it can influence the industrial park typology.The industrial park typology has gone through three generations,from land sale-oriented,building sale-oriented,to park sale-oriented.The paper explains the changes of the industrial land renewal policies in Shanghai,and takes the construction of industrial parks in different periods as an example to explore the impact of policy changes on park forms and typologies.
