本文利用2001 年至2005 年中國國家級高新技術產業園區對於經濟技術開發區吸引外人直接投資（ foreign direct investment,FDI）的影響。迴歸結果顯示，在控制區域特性後，中國國家級高新技術產業園區對於同城市內的經濟技術開發區外資流入具有正向影響，顯示高新區對於同城市內的經濟技術開發區具互補性。其互補性亦表現於高新區的出口額、銷售額以及就業情況，亦即，當高新技術產業園區的出口、銷售或者就業增加時，同城市的經濟技術開發區外資流入亦會增加。然而，高新區對於經濟技術開發區的互補效果在東部地區顯著大於西部效果，此種發展型態恐將對區域發展已不均的中國產生不利的影響。

This paper examines the relationships between two types of development zones in China, namely, the Economic Technological Development Zones (ETDZs) and Science and Technology Industrial Parks (STIPs), during the period 2001 to 2005. After controlling for regional characteristics, the results show that an ETDZ with a STIP located in the same region (city) attracts significantly more foreign direct investment (FDI), an indication of a complementary relationship between ETDZs and STIPs. This complementary relationship is reinforced by the fact that more exports, sales, or employment on the part of STIPs induces greater FDI to the ETDZs within the same region.However, the spillovers fall unevenly across regions. The ETDZs in the coastal regions benefit more from the presence of STIPs than those in the inland regions, which may lead to greater regional development disparities in China.
