Broadband China and Urban Environmental Outcomes: An Audit of Implementation, Outcome Measures, and Digital Readiness

This dataset contains the replication materials for the manuscript “Mobile Connectivity Is Not a Stand-Alone Indicator of Urban Air Quality in China: Evidence from an Auditable City Panel.” It supports an empirical assessment of the relationship between China’s Broadband China demonstration policy and urban environmental outcomes.The materials include a 2011–2019 common-support city-year panel, a panel for the linear-interpolation sensitivity analysis, a digital-readiness estimation panel, and a mechanism-analysis panel.

The variables cover policy designation and implementation, reported industrial wastewater, sulfur dioxide, smoke and dust emissions, ambient PM₂.₅ concentrations, meteorological conditions, urban economic characteristics, and digital readiness.The package also provides the scripts used to estimate the policy-outcome, digital-readiness, and mechanism models, together with the corresponding result tables, software requirements, a reproduction guide, and a source ledger.
