Abstract: By constructing a directional distance function model based on the panel data, this paper carries out a measurement of the industrial environmental technological efficiencies of 11 prefecture-level cities in Jiangxi Province between 2001-2014, then on this basis, it discusses the dynamic evolution of regional industrial production and environmental coordination. The results show that: (1) on the whole, the industrial environmental technical efficiencies of these 11 cities present a “N” type volatility trend during these years, which is far from satisfaction, the industrial developments in some areas are unsustainable because of the cost of sacrificing environment; (2) the technical efficiency in Nanchang, Shangrao and Jiujiang is in constant progress during each transition period, the rankings of Jingdezhen, Xinyu, Ganzhou and Yichun continue to decline, with less regions reaching the best practice area on the production frontier during the whole research period; (3) as a whole, the coordinated development between industry and environment is continuously optimizing and upgrading, the northern part of Jiangxi is better than the southern part of Jiangxi, especially since the 12th Five-Year Plan, the efficiency of environmental technology has been greatly promoted with significant achievements. Jiangxi province as a whole still need to optimize its energy consumption structure and industrial layout, promote actively its industrial upgrading, and carry forward the coordinated development between the regional economy and the environment.

Key words: directional distance function; industrial environmental technical efficiency; coordinated evolution
