Ever since involvement of the Binhai New Area into the national development strategy, carrying out highly effective financing promptly will play the pivotal role to implement its economic development strategy smoothly. In this paper, based on nature of regional financing, the descriptive analysis for the financing condition of the Binhai New Area is carried on. And also based on financing restraint theory and the neoclassic investment model, a real diagnosis analysis for the financing constraint condition of the Binhai New Area is studied. Finally, the existed questions in it are pointed out, and propose the correlative improvement countermeasure is put forward. 展开更多
