A lot of AH's tend to revolve around 'enlightened' rulers who encourage new technologies out of their own benefaction. As far as I can tell, in history this attitude tends to stifle industrialisation more than it advances it, simply because industrialisation and commercialisation threaten the supremacy of the nobility. Any new technologies developed in such an atmosphere would be co-opted by the King and used for his own purposes, denying their full usefulness to the general population. A more mercantalist France in which the King takes more of a back-seat to greater productive forces would result in industrialisation sooner. After all, one of the reasons Britain in the 18th century took such a great lead over other countries was that the early King Georges only spoke German, so they were obliged to entrust governance to the Prime Minister of the Parliamentary cabinet.
An analogous situation in France would be when Louis XIV was a child ruler and Cardinal Richelieu built up the centralised French state. If the one who took control during Louis' minority was instead a Parliamentarian who favoured a more...'financial' route to centralisation then we could potentially see an industrial revolution in France down the line, potentially around 1700-1750. During this time the French economy would grow massively, if haphazardly, but would eventually outrun its own resources. Consequently, a mercantalist power on the continent, whoever ruled France at the time might very well attempt a seizure of resources elsewhere in Europe, for example in the Ruhr valley. If mercantalist France wasn't as expansionist as it was during Louis XIV's reign, then it would more than make up for it from the 1750's onwards.
Britain, looking across the channel, could very well learn from the experience and industrialise accordingly, but France would still have a head-start. What consequences would this have for Europe?
