ABSTRACT
Objective@#To examine the exposure to television advertising of unhealthy food among children and adolescents in Beijing, in order to provide a basis for the formulation of marketing management policies with unhealthy food.@*Methods@#Four weekdays and four weekend days were randomly selected during October 19, 2020 to January 17, 2021, excluding holidays and school holidays. The top five popular channels of children and adolescents aged 3 to 18 years old were selected. A total of 720 hours was included for coding and analysis. World Health Organization Nutrient Profile Model for the Western Pacific Region was used to classify food and assess the health level.@*Results@#A total of 13 864 advertisings (ads) was monitored, 38.8% (5 376) of which were food ads. Furthermore, 49.9% (2 680) of food ads were unhealthy food ads, with a frequency of 2.00 per hour per channel. The top five most frequent food ads were infant formula for 12-36 months (26.7%), cheese (16.7%), savory snacks (12.2%), milk drinks (10.5%) and chocolate and candy (6.0%). The most frequently used marketing strategies for unhealthy food ads were brand benefit claims (96.8%) and promotional characters (67.9%).@*Conclusion@#Children and adolescents in Beijing are highly exposed to TV marketing of unhealthy foods. Marketing strategies such as brand benefit claims and promotional characters are employed to boost the impact of unhealthy food ads. There is an urgent need to introduce relevant policies to regulate TV marketing of unhealthy foods.
ABSTRACT
The relationship between environmental regulation and firm performance is a central question in environmental economics. Although many empirical works study this question, economists have not reached a consensus on the nature of the relationship or the mechanism that drives it. Based on the off-peak production policy in the Chinese cement market, this paper uses the differences-in-differences model to study the impact of environmental regulation on the revenue and profit of listed companies. We find that the environmental regulation has negative impacts on firms' revenue and profit. According to further analysis, the main reason for this firm performance decline is that the relatively large elasticity of market demand prevents enterprises from passing regulatory costs through to consumers. Although the policy has caused the cement price to increase by 8%, it has led cement consumption to decrease by 16%.
