In the move toward market allocation, local municipalities and provinces were allowed to invest in industries that they considered most profitable, which encouraged investment in light manufacturing. Thus, Deng's reforms shifted China's development strategy to an emphasis on light industry and export-led growth. Light industrial output was vital for a developing country coming from a low capital base. With the short gestation period, low capital requirements, and high foreign-exchange export earnings, revenues generated by light manufacturing were able to be reinvested in technologically more advanced production and further capital expenditures and investments.
