Yu, J., 2019. Real economic development model of coastal cities based on point and axis development theory. In: Guido-Aldana, P.A. and Mulahasan, S.

The regional particularity of the coastal city determines the direction of its economic development, and the economic development mode of the coastal city mainly focuses on the seafood culture, the coastal tourism and the foreign trade port, processing and so on. In order to quantify and analyze that economic development model of the coastal urban entity, the economic development model of the coastal urban entity based on the point-axis development theory is put forward. In this paper, the effective way to study the economic development of the coastal urban entities in the context of the innovation and driving development is studied, and the main difficulties facing the economic and innovation development of the current coastal urban entities are analyzed, and the development bottleneck of the economic development of the current coastal urban entities is found. The quantitative evaluation and analysis model of the economic development model of the coastal urban entity based on the quantitative regression analysis is constructed, and the panel data fusion analysis of the economic development mode of the coastal urban entity is realized by using the fuzzy comprehensive evaluation method. By adopting the fuzzy correlation constraint control method, the innovation driving planning and design of the economic development mode of the coastal urban entity is carried out, and the correlation analysis of the profit level and the profit quality of the economic enterprise of the coastal urban entity is realized. The validity of the economic development model of the coastal city is realized by combining the statistical analysis and the test method. Taking the economic example of the 200 coastal cities of China's coastal port cities as an example, the empirical analysis shows that the model can effectively and continuously innovate and drive the quantitative assessment of the economic development model of the coastal urban entities under the sustainable innovation driving strategy. The net profit rate index of the total assets of the coastal city solid economic enterprise is steadily improved, and the risk-risk ability of the coastal city solid economic enterprise is improved.
