A developmental model on quantifying urban policy effectiveness in port city relations

This paper is to find the role of urban policy in dealing with port city relations and corresponding methodology in quantifying policy effectiveness. In decomposing policy, we identify the key elements in the policy and further to measure its effectiveness. Firstly, we quantify non-linear relation in port city and explain why tradition quantitative methods fail to describe non-linear port city relationship. Secondly, we use improved logistic function derived from product life cycle theory (defined as a developmental model) to identify the evolving pattern in port city and depict the development phase and key elements. Thirdly, cases of Antwerp and Hamburg are used in analyzing how urban policy is effective in enhancing port city relations. It is difficult to quantify policy effectiveness thus we focus on how key elements in these policies are enhanced in promoting port city development even though port city are at different developmental phases and these policies can solve conflict between private port governance and public urban nature.
