  To contain the pandemic of coronavirus (COVID-19) in Mainland China, the
authorities have put in place a series of measures, including quarantines,
social distancing, and travel restrictions. While these strategies have
effectively dealt with the critical situations of outbreaks, the combination of
the pandemic and mobility controls has slowed China's economic growth,
resulting in the first quarterly decline of Gross Domestic Product (GDP) since
GDP began to be calculated, in 1992. To characterize the potential shrinkage of
the domestic economy, from the perspective of mobility, we propose two new
economic indicators: the New Venues Created (NVC) and the Volumes of Visits to
Venue (V^3), as the complementary measures to domestic investments and
consumption activities, using the data of Baidu Maps. The historical records of
these two indicators demonstrated strong correlations with the past figures of
Chinese GDP, while the status quo has dramatically changed this year, due to
the pandemic. We hereby presented a quantitative analysis to project the impact
of the pandemic on economies, using the recent trends of NVC and V^3. We found
that the most affected sectors would be travel-dependent businesses, such as
hotels, educational institutes, and public transportation, while the sectors
that are mandatory to human life, such as workplaces, residential areas,
restaurants, and shopping sites, have been recovering rapidly. Analysis at the
provincial level showed that the self-sufficient and self-sustainable economic
regions, with internal supplies, production, and consumption, have recovered
faster than those regions relying on global supply chains.
