中文摘要：

进入21世纪,开发区导向的中国郊区化发展步入了新阶段。基于外部环境和自身诉求的共同影响,在新一轮城市发展战略指引下,许多大城市的开发区进入转型与再开发的战略期。基于转型的路径与主导机制不同,文章选取广州市域范围内两个国家级经济技术开发区—增城和南沙经济技术开发区为案例,探讨国家级经济技术开发区转型的路径与机制,并提出国家级经济技术开发区转型的两个阶段：在产城联动阶段,承接部分城市功能,与紧邻城区错位提升;在产城融合阶段,在产城联动基础之上,承载综合城市功能,自身向新城市或新城区转型。通过对比增城和南沙经济技术开发区在转型不同阶段中的不同机制,以期为我国其他开发区的转型发展提供有益借鉴。
