Based on the panel data of 18 industrialsectors 1996-2011, this paper analyzes three kinds of change rate of environmental regulation intensity's effects towards the change rate of production technological progress from the perspective of change rate by using panel threshold technology. The results show that: (1) the influences of the change rate of exhaust gas, waste water and solid waste's environmental regulation intensity towards the change rate of production technological progress all has two thresholds. Only a proper change rate of environmental regulation intensity can lead to a desired change rate of production technological progress. But there are quite differences in the thresholds of the change rate of such three kinds of environmental regulation intensity, and the optimal change rates are (14.93%,53.18%], (16.96%,37.75%] and (32.90%,48.11%] respectively; (2) in the change rate of exhaust gas and waste water's environmental regulation intensity, 8 and 4 sectors are at a reasonable level, and the remaining 10 and 14 sectors are below reasonable level; as to solid waste, 2 sectors are at a reasonable level, 9 sectors are below reasonable level, and the remaining 7 sectors are higher than reasonable level. Hence, in order to achieve a "win-win" situation between environmental protection and production technological progress, different environmental regulation intensity should be used according to different pollutants of various industries.
