Retail spending, which supplied 80% of China's economic growth last year, plunged 19% in the first quarter from a year earlier, below most forecasts. Investment in factories and other fixed assets, the other major growth driver, sank 16.1%.
On a quarter-on-quarter basis, GDP fell 9.8% in the first three months of the year, the National Bureau of Statistics said, just off expectations for a 9.9% contraction, and compared with 1.5% growth in the previous quarter.
Separate data showed China's industrial output falling by a less-than-expected 1.1% in March from a year earlier. Retail sales fell 15.8% in the same period. Fixed asset investment shrank 16.1% in January-March.
China's urban jobless rate was at 5.9% in March, down from 6.2% in February.
Auto sales sank 48.4% from a year earlier in March. That was better than February's record 81.7% plunge but is on top of a 2-year-old decline that already was squeezing global and Chinese automakers in the industry's biggest global market.
Exports declined 6.6% in March from a year ago. That was an improvement over the double-digit plunge in January and February, but forecasters warn exporters likely face another downturn as the fight against the virus depresses US and European consumer demand.
