Abstract：Huaqiangbei in Shenzhen, known as “China’s No. 1 Electronics Street”, has become a global hub for electronics
manufacturing and trade due to its unique commercial ecosystem and highly concentrated industrial chain. However,
with rapid urban development, the area now faces challenges such as inefficient land use, severe traffic congestion,
and aging infrastructure. In recent years, Shenzhen’s municipal government and relevant departments have actively
promoted spatial governance innovation in Huaqiangbei, exploring data-driven, refined management strategies for
built-up urban areas to enhance vitality and sustainable development. This study integrates multi-source data—
including demographics, industry, and transportation—to construct a two- and three-dimensional digital urban base,
enabling holographic management and dynamic optimization of urban space. Governance strategies have shifted
from traditional blueprint-style planning to design-led urban governance. Focusing on data-driven decision-making
and multidimensional governance methods, this paper examines innovative practices in Huaqiangbei and explores the
application potential and demonstration value of big data technologies in the spatial governance of built-up urban areas.
