目前，中國大陸最熱門的兩大經濟區域為長江三角洲與珠江三角洲，此兩地吸引眾多外商至當地投資。究竟此兩區域具有何區位優勢能吸引眾多外資，以及此兩地區的優勢有何差異，成為本論文重心所在。本論文主要探討三個主題： 一﹑這兩區域自改革開放以來，區位優勢的消長如何，才造成今日長江三角洲吸引外商投資金額超越珠江三角洲。 二﹑這兩區域有何區位優勢，才能吸引眾多外商至當地投資。 三﹑這兩區域與中國大陸整體平均水準的區位優勢作比較，究竟這兩區域相較於中國大陸整體平均水準具有何優勢，使外商特別關注此兩大地區。 以上問題運用中國統計年鑑的數據資料，以複回歸模型分析各地區的外商投資數據，以得出各項主題的結果。 / Yangtze River Delta and Pearl River Delta are both the most famous economic areas in Mainland China nowadays, attracting many foreign capitals to invest. The purpose of this thesis is to investigate what are the advantages in these two areas that attract foreign direct investment, and what are the differences between them. Three subjects are discussed in the present study.

Third, what are the unique location advantages in these two areas compared with the average level of Mainland China, so that many foreign investment enterprises pay especially high attention to this two areas. Data of Statistical Yearbook of China are used in the present study, and multiple regression model is adopted to analyze the data in order to obtain the results.
