چکیده
By analyzing the granted patents distribution of the energy-saving and environmental protection industry in China from 2008 to 2013, the conclusion can be reached: firstly, technological innovations of the energy-saving industry are focused on the environmentally air-conditioning and heat pump technical field, and technological innovations of the resources recycling industry is mainly concentrated on the food waste treatment and comprehensive utilization technical field and the urban sewage sludge recycling technical field, and technological innovations of the environmental management industry is highly focused on the high concentration organic wastewater control technical field; secondly, the granted patents distributions of the key strategic technical fields are unbalanced, of which the granted patents of the environmental management industry have the largest share; thirdly, the domestic granted patents distributions are basically similar to that of foreign granted patents in the energy-saving and environmental protection industry in China, but the domestic granted patents numbers are more than the foreign granted patents numbers.
