This study introduces the concept of "perceptual synergy" to systematically examine how the interplay between social perceptions (products/services) and environmental perceptions shapes retail density. It utilizes proprietary data collected from Dianping.com (shop locations and attributes) and the Baidu Maps API (Street View Imagery). As these datasets are the intellectual property of their respective commercial entities, they cannot be shared publicly. To facilitate transparency and reproducibility, the derived datasets generated for the analysis presented in this paper have been deposited here.
