摘 要在经济全球化不断深入的今天，的不断推进，进出口贸易和国民经济得到了高速发展，并且发展事态良好。然而，随着全面高速发展，在经济全球化的大背景下，经济发展仍然存在一些小问题。本文通过搜集时间序列数据（1980—2018），并且基于进出口总额和GDP 数据，运用经济学的相关计量方法对相关数据进行单位根检验、协整分析和 Granger检验，得出进口额、出口额、和进出口贸易结构能够促进经济增长，三者之间存在单向Granger 因果关系的结论。本文在最后，根据研究分析，提出了相应的解决对策。关键词：贸易现状 ；国民经济；实证分析ABSTRACTWith the continuous advancement of economic globalization, the import and export trade and the national economy have shown rapid development, and their development momentum is very alarming. However, in the context of this all-round high-speed development, economic development still has problems in small areas. This paper collects time series data from 1980 to 2018. Based on the total input and export and GDP data, this paper uses the econometric method to perform unit root test, cointegration analysis and Granger test on relevant data. Imports, exports, and import and export trade structures can promote economic growth, and there is a one-way Granger causal relationship between the three and economic growth. Finally, the corresponding countermeasures are proposed..Key words:Trade status; national economy; empirical analysis目录1 绪论...............................................................................................................................................11.1 选题背景及研究意义.........................................................................................................11.2 研究现状.............................................................................................................................11.3 研究思路和方法...........................................................................................
