中文摘要：

针对外资在华集聚,验证了生产性服务业FDI与东道国技术溢出的关联格局与溢出绩效改进影响要素。结果证实,长三角区域生产性服务业FDI空间关联与区域的技术溢出改进关联强度具有热点高值簇偏少、次热点广而绩效扩散不均匀特征和递减加速的负向渗透规律;在150km距离范围内,外部资本和市场化程度、劳动力及开放程度分别构成江苏省、浙江省和上海市获自生产性服务业FDI与东道国技术溢出改进的主要关联因素。

英文摘要：

This paper tests the correlation patterns between the producer services industry＇s FDI and spillovers in host countries, as well as the influencing factors for improving the performance of spillovers. The results show that there are inhomogeneous features of rare hot spots, extensive sub- hot but non- uniform diffusion performance, and a pattern of deceleration of negative permeability in the Yangtze River Delta. Within a radius of 150 km, external capital, the degree of marketization, labor, and the degree of market openness constitute the main factors of technology innovation spillovers in Jiangsu Province, Zhejiang Province, and Shanghai.
