(Local policies and subjective wishes are other aspects). We can also find that the decreasing of foreign capital from the intensive decreasing of the proportion of foreign capital over the total social investment. The proportion of foreign capital was 20.66% in 1995,the utilization of foreign capital has already entered the new stage of stable or decreasing scale.
