Abstract: According to the basic data from 1991 to 2014 of five kinds and provinces mineral resources industry chains，use the DEA model of CCR、BCC and super efficiency model to measure the technology efficiency of the whole and different kinds of mineral resources industry chains，and to analyze the spatial-temporal characteristics of technology efficiency about mineral resources industry chains.The results showed that the whole，different kinds and provinces technology efficiency of mineral resources industry chains have achieved varying degrees increase，the pure technology efficiency of mineral resources industry chains contributed significantly lower than the scale efficiency；technology efficiency spatial-temporal distribution of mineral resources industry chains presented basically the economic development and the technical level of the eastern，central and the western region；based on industry chains，industry and enterprises to cultivate regional innovation network clusters，constantly to improve the technology content and technology contribution ratio，which is a realistic path of industry chains achieve technology efficiency，scale efficiency，resources efficiency and environment efficiency coordinated development.
