Abstract:Over the past few decades, mainland China has reformed restrictions on its port investment in order to meet the huge demand of related infrastructure, especially promulgated the deregulation of foreign investment into container port. Nowadays, port investments have included the state investment, bank loans, self-raised funds, foreign investment and IPO and so on. We focus on investment optimization of container capacity with the basics of the model proposed, putting forth some conclusions and policy recommendations through conducting numerical illustration of the Shanghai case.
