横沙新港建设的经济合理性研究

摘要 以上海港为研究对象, 重点就港口与城市发展关系进行了研究.首先运用线性回归模型对港口数据与城市\,GDP\,进行了分析,并以此模型对横沙建港后上海城市经济情况进行了预测分析. 此外,针对线性模型中可能产生的偏差, 又建立了基于非线性关系的神经网络模型,并以此进行相应的预测. 通过采用以上量化分析方法,可以预计横沙成陆建港将带动相关产业的发展,从而带来一定程度的经济效益,对上海的城市发展建设有着积极的作用和不可忽视的影响.
Abstract：Based on current situation of Shanghai Port, this paper focuses on the relationship between port and the development of city. First, data of port and GDP of city are analyzed making use of the linear regression model. Furthermore, the influence on economy in Shanghai after Hengsha new terminal is predicted.Considering the possible deviation in the linear model, however, a neural network model is established to forecast corresponding results. By the above quantitative analysis methods, Hengsha new terminal is expected to drive the development of related industries, bring economic benefits to some extent. In other words, Hengsha new terminal has positive and significant influence on development and construction of Shanghai.
