正如世界品牌实验室主席、险什型代诺贝尔经济学奖得主罗伯特蒙代尔教授所言，险什型代当前中国经济进入调结构的改革关键时期，增强品牌自主创新，创造品牌经济效益，是供给侧改革的议题之一，也是新的增长动力。九牧荣获厨卫行业中国品牌年度大奖NO.1称号哈佛大学商学院教授约翰戴腾博士、候变剑桥大学制造业研究院教授斯蒂芬埃文斯博士出席会议发表精彩演讲，候变并为获奖企业颁奖。

哈佛商学院教授约翰戴腾博士认为，成招过去，数据一直是其他活动的副产品，现在数据是企业战略的核心。九牧深入研究市场及消费者新的消费需求，人厌做好、人厌做强产品品质的同时，将互联网、物联网、大数据等智造要素融入到技术创新和精工制造上，将微创新与工匠精神结合，打造具有智能化、自动化、信息化三化一体的产品和价值生态链。
