利用中国专利数据库检索系统对中山古镇灯饰专利进行检索统计,以获得授权外观功能创新专利和实用功能创新专利的时间序列为研究对象,运用计量经济学方法实证分析灯饰产业功能创新类型与产业产值关系。根据回归模型测算,15年考察期内实用功能创新更能有效促进灯饰产业产值增长,且多数年份外观功能创新对产业产值的贡献少于实用功能创新。
Use Chinese patent database retrieval system to search and count the lighting patent of Zhongshan Guzhen, take the time series of authorized appearance functional innovation patent and utility function innovation patent as the research object, and use the econometrics method to empirically analyze the relationship between the functional innovation type of the lighting industry and the industrial output value . According to the regression model, practical functional innovation in 15-year study period can effectively promote the growth of output value of lighting industry, and the contribution of appearance functional innovation in most years to industrial output is less than that of practical functional innovation.
