Abstract：Currently, the efficiency evaluation of manufacturing industry has neglected the energy and environment cost. In this research, the authors calculate the environmental technology efficiency of various sub-industries in manufacturing industry from the year 1999 to 2007. A non-parametric environmental production approach is adopted in the calculation. In this model, the calculated output not only includes the industry output growth, but also considers the contaminations. Also, 28 industries in manufacturing sector are chosen as research objects and a linear programming method is adopted to calculate the industry efficiency. The manufacturing growth model with the constraints of resources and environment is studied and the feasibility of manufacturing growth mode is analyzed. The authors conclude that the manufacturing environmental technology efficiency in China shows an obvious improving trend. During the process of research, the industries including "tobacco", "leather, fur feathers (down) and its sub-products", "communication equipments and computers" and "electronic equipment manufacturing industries", reach high efficiency in environmental technology. These industries have achieved the ideal situation that the output grows, the resource consumption decreases, and the emission of pollution reduces. The environmental efficiencies of the rest industries are lower than the above industries, none of which reaches the standard. The year of 2003 is a turning point of manufacturing industry, light industry and heavy industry in environmental technology efficiency. The regression results show that with the help of the existing technology, it is feasible to make some change in the high energy consumption, high pollution and extensive mode in manufacturing industry. Therefore, a diversion from the extensive mode of "high input, low output and high emissions" to the intensive mode of "low input, high output and low emissions" can be achieved.
