中文摘要：

随着世界经济一体化和我国改革开放的不断深入，外国直接投资作为我国投资的重要来源与我国经济增长之间存在密切关系。我们通过Granger影响关系检验和协整关系检验对外国直接投资与我国经济增长之间的关系进行分析发现，外国直接投资对国内产出具有显著的单向影响，说明外国直接投资对我国经济增长起到了重要的推动和促进作用。同时，我们发现外国直接投资与国内产出之间的长期均衡出现偏离是导致投资和产出波动的重要原因。

英文摘要：

As the most important source of investment of our country, the foreign direct investment and economic growth of our country have close relations between each other. We test the relationship between them by using Granger Causality test and error correction model and find that the foreign direct investment has a significant impact on the domestic output on the one-way which means that foreign direct investment have promoted the economic growth of our country markedly. At the same time, the departure from the long-term balance in investment and output is the major cause of the fluctuations of the investment and output in our country.
