Regardless of a customer’s social status, wealth, or country of origin, Apple products have been notorious for establishing trends in regard to electronic devices. As of 2019, China accounted for 17% percent of all Apple sales. This has been made possible in large part due to Chinese customers’ favorable image of the Apple brand and the positive experience with Apple products. This study aimed to examine the impact of brand experience, brand love, and brand engagement on brand equity. The brand-love mediation role between brand experience and brand engagement/brand equity was also explored. The conceptual framework was supported by social exchange and attribution theories. According to the analysis of 339 respondents from China, brand experience, brand love, and brand engagement significantly positively affects Apple’s brand equity. Additionally, it was discovered that brand love demonstrates a significant mediating role between brand experience and brand engagement/brand equity. These findings can aid other manufacturers offering similar electronic products in China to adapt their marketing and competitive strategies in order to boost their brand equity and as a result sales revenue.

Because of people's increasing demand for water resources and excess usage of existing water, water shortage exists in many countries. Accordingly, the research on how to solve the water scarcity is of great value. Considering the dynamic influence of time on water resource supply and demand and the two factors including the degree of water resource exploitation and per capita availability of water, the water resource supply and demand model is built to measure the capacity of the region to offer clean water. Building up the grey prediction model to predict the following 15years' population situation and the total water resource supply in north China. By combining the model in before, the result that the demand for water resource is greater than the supply is concluded, which means severe water scarcity. The water scarcity causes the decrease of agricultural planting output, the change of planting structure, the reduction of industrial agglomeration and the residents' daily usage of water not reaching the living standard.
