本文以工业部门18个行业1996-2011年的面板数据为样本,从变化率的角度,使用面板门槛技术研究了三种环境规制强度变化率对生产技术进步变化率的非线性影响,研究结果表明:(1)废气、废水和固废三种环境规制强度变化率对生产技术进步变化率的影响均存在两个门槛效应,只有适度的环境规制强度变化率才能引致理想的生产技术进步变化率,但三种环境规制强度变化率指标的门槛值有较大差异,最优环境规制强度变化率区间分别为(14.93%,53.18%)、(16.96%,37.75%)和(32.90%,48.11%);(2)在废气和废水环境规制强度变化率上,分别有8个和4个行业处于合理水平,其余10个和14个行业低于合理水平;在固废环境规制强度变化率上,有2个行业处于合理水平,9个行业低于合理水平,其余7个行业则高于合理水平。因此,为实现环境保护和生产技术进步的"双赢",可以有针对性地对各行业的不同污染物制定有差异性的环境规制强度。
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 rea- sonable 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.
