Dynamic Characteristic of Consumer Attention in Online Reviews —Empirical Research Based on Mobile Store Reviews

Nowadays consumer online reviews are becoming more and more important for enterprise decision-making. While the existing research seldom discussed review data from a dynamic perspective, especially ignored consumers\u27 attention change during the product life cycle. To study whether there are dynamic changes and the characteristics of changes in the attention degree of consumers in each phase of the product life cycle, this paper coded a specific node program to collect the online reviews data of the four mobile phones in the entire product life cycle and used python\u27s Chinese automatic word segmentation tool library to segment each word and count word frequency, and then a stepwise regression method was used to analyze the dynamic changes of consumer attention. The paper finds that consumers’ attention on logistics and products presented in online reviews show a downward trend, and the attention on brands shows an upward trend; There is no obvious change in the attention degree on services, prices, and promotion; On the different dimensions of products, there is a significant difference in the attention degree. The research results broad the research ideas of online reviews, provide decision-making basis for enterprises to grasp the characteristics of consumers at different stages and to formulate production and marketing strategies

Exploring Cumulative Vulnerability of Mangrove Forests to Intensive Coastal Anthropogenic Threats

Mangrove forests, as the most productive coastal ecosystems in tropical and subtropical regions, provide essential ecosystem services to coastal communities. However, intensive coastal anthropogenic threats have resulted in a dramatic decline in mangrove coverage throughout many developing regions. Therefore, it is urgent to investigate the cumulative vulnerability of mangroves to these anthropogenic threats. Here, we used geospatial datasets and the “exposure–sensitivity–resilience” conceptual framework to evaluate spatial vulnerability of mangroves in mainland China in 2020. We found that nearly 68% of mangrove areas in mainland China were identified with medium to high vulnerability. Land-based pollution and coastal aquaculture expansion were the main threats leading to high vulnerability in the whole study area, but the principal drivers of mangrove vulnerability at local scale were various. The vulnerability hotspots induced by pollution and aquaculture were mostly located in Guangdong and Fujian Province, and those regions exposed to sea-level rise were concentrated in Hainan Province. Our study provides the first dataset of spatially explicit-based solution for reducing mangrove vulnerability to intensive coastal anthropogenic threats on a national scale. The spatial distribution of principal vulnerability drivers could provide a guideline for mangrove conservation and coastal-ecosystem-based management
