1978年的经济开放为中国铺展了融入全球经济之路。一方面，通过实施优惠政策，中国政府鼓励大量的外国直接投资的流入；另一方面，中国进入21世纪以来加快了对外直接投资的步伐，尤其是“一带一路”倡议的提出为“走出去”提供了战略支撑。广东是目前中国吸引外商（含港澳台）直接投资最多的省份，同时在对外投资方面也一直走在全国其他省份的前面，其对外投资存量超过第二名上海市将近一倍。鉴于此，本文尝试对广东双向投资的发展历程进行系统的梳理与分析，在当前对外开放40年的背景下，这项研究是很有必要的，可以为广东省总结开放的经验与不足，为加快利用双向投资促进经济转型升级提供经验证据支撑和政策建议。
The economic opening in1978 has laid the way for China to integrate into the global economy.On the one hand，through the implementation of preferential policies，the Chinese government encourages large amounts of foreign direct investment inflows；on the other hand，since the beginning of the new century China has speeded up the pace of outbound direct investment.Particularly，putting forward the “One Belt，One Road” initiative provides support for the strategy of “Going Out”.Among all the Chinese provinces，Guangdong stands at the top location of attracting foreign businessmen （including investment from Hong Kong，Macao and Taiwan）.At the same time，it has been in the front of other provinces in terms of outbound direct investment.The stock of outbound direct investment from Guangdong is nearly twice that from Shanghai，the second largest source of outbound investment in China.In view of this，this article will try to combine with the carding and analysis of the development of two-way investment in Guangdong.Under the background of the opening up for 40 years，the study is very necessary.Through summarizing the experience and analyzing the shortcomings of opening up，this study will provide empirical evidence and policy suggestions to accelerate the use of two-way investment to promote economic transformation and upgrading.
