Abstract
This study explores the diversification of high-quality technologies within Chinese cities from 2000 to 2015. Our results reveal that both high-quality and low-quality technological portfolios contribute to high-quality technological diversification. High-quality portfolios dominate this process as provide high-value knowledge that can be shared with new related technologies. Meanwhile, low-quality portfolios play a complementary role in this process by facilitating local knowledge deepening, in which existing low-value knowledge gradually evolves into high-value one through local interaction. Moreover, technological relatedness and interregional spillovers are substitutable when contributing to the diversification of high-quality technologies.
期刊介绍：
Regional Science is the official journal of the Regional Science Association International. It encourages high quality scholarship on a broad range of topics in the field of regional science. These topics include, but are not limited to, behavioral modeling of location, transportation, and migration decisions, land use and urban development, interindustry analysis, environmental and ecological analysis, resource management, urban and regional policy analysis, geographical information systems, and spatial statistics. The journal publishes papers that make a new contribution to the theory, methods and models related to urban and regional (or spatial) matters.
