The Nikkei Flash Japan Manufacturing Purchasing Managers' Index, or PMI, rose to 53.8 in November from 52.8 in October.
The reading remained above the 50 threshold that separates expansion from contraction for the 15th consecutive month and marked the fastest expansion since March 2014.
Chris Williamson, the firm's chief business economist, said business across the eurozone is "booming", and noted jobs are being created at the fastest rate since the dot.com era in the early part of the new century. The flash composite output index rose to 57.6 in November from 56.6 in October. However, economists say consumption and business investment will start to accelerate soon and expect domestic demand to drive growth in the future.
"The PMI is so far running at a level signaling a 0.8% increase in GDP in the final quarter of 2017, which would round-off the best year for a decade".
"The latest numbers suggest the night is still young with regard to the French private sector's economic recovery".
Alex Gill at IHS Markit said: "The party goes on for the French private sector economy".
The strong growth and falling unemployment should in time help fuel price increases in the economy.
