the data of paper Efficiency of policy responses to public emergency in the construction industry: A surveyof China

Effective policy responses to urgent situations such as the COVID-19 pandemic are critical for the construction industry to increase its resilience. Therefore, it is essential to understand the underlying correlation mechanisms that determine spatiotemporal response efficiency. This study investigates the efficiency of policy implementation involving public emergency prevention and control of construction costs.A survey was conducted to collect responses during a representative period of the COVID-19 pandemic (Q1 2020 - Q3 2022) across 31 provinces in China. The data analysis employed a Zero-inflated Poisson regression model to explore efficiency mechanisms in five dimensions. The findings suggest that policy-response efficiency follows a 'U' shaped trend over time. Furthermore, the absolute construction scale was not significantly associated with response efficiency, whereas the relative scale hindered its improvement. The younger age of key leaders in housing and construction departments has a positive effect, although its impact is small. Local fiscal extractive capacity is not a key factor influencing response efficiency, but higher fiscal allocation capacity reduces its level. A higher recovery capacity from public emergencies is the main driver for the improvement of response efficiency, while the severity of public emergencies has the opposite effect. Finally, the study observes that vertical hierarchical pressure is not conducive to response efficiency, and pressure from neighboring provinces plays a minor role. These findings provide valuable insights for improving the response efficiency of the construction industry to emergencies.
