Abstract Regional economic disparities have great influences on national economy and social development which cannot be ignored, and it has been one of the core issues of research on regional economics. The paper took 1990-2017 as the research period and 63 counties in Yangtze River Delta (YRD) as the research object, using the coefficient of variation, Theil index and its second order decomposition to calculate the overall and internal economic differences. The paper analyzed the spatial pattern of economic differences based on ESDA method, and used the spatial regression model to explore globalization, marketization, decentralization and localization in the mechanism of economic differences of counties in YRD. The results showed that: (1) From 1990 to 2017, the overall economic differences of counties showed a trend of convergence. As for YRD, the regional inequality is more obvious in small scale units. (2) From 1990 to 2017, there was a significant positive spatial correlation among the economy of YRD, and the county economy showed a polarized trend with an overall unbalanced development, while the local economic development in YRD is relatively coordinated. (3) Globalization, marketization, decentralization and localization all participate in the formation of regional inequality. To be specific, decentralization has a significant role in promoting economic growth in each period, marketization has greater influence in the early 1990s, and globalization is the most influential factor in the early 21st century. Localization has always been an important factor for the increase of regional disparities in YRD, especially the industrialization level and the capital scale. The impact of the quantity of labor force on regional inequality has gradually turned from a negative effect to a positive effect under the new circumstances.
