BEIJING — The announcement Saturday that Foxconn Technology — one of the world’s largest electronics manufacturers — will sharply raise salaries and reduce overtime at its Chinese factories signals that pressure from workers, international markets and concerns among Western consumers about working conditions is driving a fundamental shift that could accelerate an already rapidly changing Chinese economy.

But the true meaning of Foxconn’s reforms, analysts say, will depend in part on how effectively the company can remake an economic system that has relied for much of the last decade on luring migrants to work cheaply for long hours in mammoth factories building smartphones, computers and other electronics.

Plants depend on workers’ being at assembly lines six or seven days a week, often for as long as 14 hours a day. Such facilities have made it possible for devices to be turned out almost as quickly as they are dreamed up.

For that system to genuinely change, Foxconn, its competitors and their clients — which include Apple, Hewlett-Packard, Dell and the world’s other large electronics firms — must convince consumers in America and elsewhere that improving factories to benefit workers is worth the higher prices of goods.
