The HCOB France flash purchasing managers index (PMI) for the services sector in November, compiled by S&P Global, came in at 45.3 points.
This was marginally better than 45.2 points in October but below the 50 points level indicating a contraction in activity. It was also below a Reuters poll forecast for a November flash services PMI of 45.6 points.
The flash manufacturing PMI for November fell to 42.6 points from 42.8 in October, and also came in below a Reuters poll forecast for a figure of 43.1 points.
"The French economy is kind of in a dead-end. Output has declined for the sixth month in a row, especially precipitated by lower demand overall and from abroad. Both sectors' activity levels – manufacturing and services – declined significantly in November," said Hamburg Commercial Bank economist Norman Liebke.
"The inflation threat remains at large. The latest PMI data indicate that prices are still rising sharply, suggesting that official inflation statistics could remain at higher-than-anticipated levels for longer than previously thought," he added.
Elsewhere, France has announced that it will will sign several deals with China during Foreign Minister Catherine Colonna's official visit to China this week, said the French foreign ministry on Wednesday.
Earlier this week, Chinese President Xi Jinping said China wanted more French companies to invest in the country, as Xi held a phone call with French President Emmanuel Macron.
