Abstract
The information technology revolution has changed people's original way of production and life, and the pseudo human settlements (PHS) constructed through digital and information have thoroughly permeated and influenced individuals' daily lives. However, the theoretical foundation and practical research on the interrelationships and interactions of the systems of the PHS are not yet mature, consequently, establishing a theoretical framework for the coupling coordination of PHS and empirically analyzing the spatiotemporal characteristics of coupling coordination in the urban agglomeration of eastern China and the driving mechanism, employing models such as coupling coordination. The results demonstrate that PHS within the urban agglomeration of eastern China displays a temporal upward trend resembling an "inverted L," a spatial trend of "high in the north and low in the south," and a positively correlated spatial cluster trend. The center of gravity of the coupling coordination degree tends to shift from the northeast to the southwest, suggesting a faster growth of the coupling coordination degree in the southwest direction compared to the northeast. The coupling coordination of PHS results from the combined influence of multiple factors and systems, and the optimization and enhancement of the PHS need to be based on the reality human settlements (RHS).
