The impact that environmental regulation has on technology innovation is a hot spot in currently research which already has a large number of empirical studies based on Porter Hypothesis． However there are still controversies in academia about the establishment of weak Porter Hypothesis and narrow Porter Hypothesis． Based on the panel data of application for patent of emission reduction technology of 285 prefectural-level municipalities during 2008 － 2014， comprehensive energy price， and pollutant emission etc． ， we use mixed regression model and systematic GMM method respectively to study the impact that market-oriented policy tool and command-and-control policy tool have on China energy conservation and emission reduction technology innovation． The results show that the environmental regulation hinders the technological innovation at sight however promoting it after lag one issue． So the establishment of weak Porter Hypothesis has time constraints． The lag command-and-control policy tool plays a more positive role in promoting technological innovation than market-oriented policy tool， so narrow Porter Hypothesis couldn’t work． The reason is that the main participants of China energy-saving and emission reduction technology innovation are state-owned enterprises and public institutions．Regionally speaking， the impact which command-and-control policy tool has on technological innovation at sight is non-significant in eastern， central and western regions; market-oriented policy tool has negative effect． And market-oriented policy tool in central region has strongest negative effect， it will diminish in eastern region and become weakest in western region． This is related to regional energy consumption level and the market economic vitality． The research firstly finds that the narrow Porter Hypothesis is not suitable for China emission reduction innovation while the weak Porter Hypothesis works， secondly it provides reference for the formulation of regional energy saving and emission reduction policies.
