Abstract: Based on the data of 233 urbans in China from 2000 to 2016, this paper examines whether national high-tech zones can improve urban innovation efficiency through the PSM-DID model, and then organizes the heterogeneity test from the insight of urban size and urban grade. Further, spatial agglomeration is introduced as a moderating variable to explore an internal path of national high-tech zones on urban innovation efficiency from the insight of production factor agglomeration and industrial agglomeration. Our empirical results indicate that national high-tech zones can significantly improve urban R&D efficiency and technology transformation efficiency. What's more, the effect of national high-tech zones on urban innovation efficiency varies with both urban size and urban grade, which is embodied in the fact that the improvement of national high-tech zones on innovation efficiency of large, medium-sized, and small cities is superior to mega-cities, and such improvement in second-and third-tier cities is better than that in fourth-and fifth-tier cities, while it does not affect the achievement transformation. Based on the results of spatial agglomeration regulation effect, it can be concluded that factor agglomeration significantly positively moderates the effect of national high-tech zones on R&D efficiency and technology transformation efficiency, but industrial agglomeration significantly negatively moderates the effect of national high-tech zones on technology transformation efficiency. In additional, factor agglomeration and industrial agglomeration have an obvious heterogeneity in moderating the innovation efficiency of cities in eastern and mid-western China. This paper expands the transmission mechanism of the driving role of national high-tech zone, and also provides factual evidence for exploring the path of improving urban innovation efficiency.

Key words: national high-tech zones, urban innovation efficiency, factor agglomeration, industrial agglomeration
