Abstract: Based on the angle of value chain, the technology innovation is divided into two stages of R&D and S&T achievement conversion. And then, we put technology innovation’s environmental impacts into the measurement framework of S&T inversion, and make it as undesirable outputs in the second phase. By the method of nonparametric meta-frontier and DEA model , the analysis and comparison have been made on the regional disparities of China’s provincial industrial enterprise’s technology innovation efficiency during the period of 2003-2010.Additionally, a quantitative Technology Gap Ratios(TGR) has been made on the technology gap between the areas in utilizing innovation resources. Subsequently, In order to find out the root cause of inefficiency innovation, we decompose the inefficiency by the two dimensions of “innovative production technology” and “management”. The research show that: Industrial enterprise’s R&D and S&T inversion efficiency in China are low during the examining period. the efficiency averages are only 0.683 and 0.691 under the meta-frontier; During the period, R&D and S&T inversion efficiency’s regional disparities are significant. The TGR of middle and western efficiencies are low, especially in stage of S&T inversion; R&D and conversion inefficiency in the eastern state almost stems from the low level of management, while the central and western provinces main be subjected by the two aspects of area inefficient technology and business management, For a few central and western provinces (e.g., Neimenggu), the backward level of region technical is the main reason.
