The urban population agglomeration capacity and its impact on economic efficiency in the Yangtze River Delta Urban Agglomeration

Abstract This paper constructs and elaborates a theoretical model of urban economic efficiency (UEE) from the perspective scaling law. A framework analysis is established with population agglomeration capacity (UPAC) as explanatory factor. Taking Yangtze River Delta Urban Agglomeration (YRDUA) case study, explore influence UPAC on UEE. The results show that gap between UEE in YRDUA gradually decreases, spatial characteristic weakens, among cities leads to balanced tendency. However, pattern becomes more significant. (Mega/super) large are mostly advanced types, while small lagging types. decreases diverges significant positive insignificant cities. research provides objective way understand compare performance different scales. empirical study findings provide basis for decision-making developing types
