Abstract:

A clear green growth development mechanism of port-city can provide "reference" for local government to promote green transformation of port-city. The paper develops a green growth development mechanism of port-city which contains dual mechanism of co-evolutionary growth and resource constraint from the comprehensive perspective of local government. Subsequently, a nonlinear optimal control model is established to quantitatively describe the green growth process that shows how subjective and objective control factors have effect on natural capital and physical capital to maximize the economic benefits of port-city. By analyzing the case of the port-city of Tangshan, the results show that a promising future for green growth of port-city lies in the "balance" between port-city' GDP and port's cargo-handling capacity under the mechanism of co-evolutionary growth, and satisfying the basic conditions for port-city coastal resources is the necessary prerequisite for green growth of a port-city.
