Combined with theoretical and empirical analysis, the effect of “InternetPlus” on the upgrading of residents' consumption is studied from the perspective of effective supply of consumer goods. The results show that the improvement of the level of “InternetPlus” in China is conducive to driving the upgrading of residents' consumption, and the trend of consumption upgrading of urban residents is more obvious than that of rural residents. The improvement of the level of “InternetPlus” can significantly improve the R&D innovation ability of manufacturers and then promote the upgrading of residents' consumption, but there are significant differences in the role played by different types of R&D and innovation. Specifically, high-end technological innovation has played a significant role in promoting the consumption upgrading of urban and rural residents, while middle-end model innovation has only played a significant role in promoting the consumption upgrading of rural residents. However, the effect of low-end design innovation on the consumption upgrading of urban and rural residents is not obvious.The development model of "Internet" in China has an obvious preference of attaching importance to the innovation at the end of the industry while neglecting the innovation in the front and middle of the industry. This path-dependent behavior makes the improvement of R&D intensity lead to an increasing trend of the influence effect of “InternetPlus”enabling design innovation, while the influence effect of enabling technology and model innovation shows a significant decreasing trend. When the R&D intensity is in the range of 2.877% , the “InternetPlus” development significantly increases the investment in design innovation of manufacturers and helps to increase the added value of consumer goods, but as the R&D intensity exceeds the 2.877% level, the benefits of product appearance innovation are gradually diluted and squeezed out the investment of middle and high-end technological innovation, and the role of promoting the upgrading of household consumption is also gradually weakened. Based on the above research conclusions, argeted policy recommendations are putforward .
