Biodegradable plastics are a new type of plastic with negative carbon emissions, derived from renewable resources and capable of being broken down by biological processes, thus meeting environmental sustainability and net-zero carbon emission goals. Due to these characteristics, biodegradable plastics are gradually becoming a common replacement for traditional plastics that cause plastic waste and microplastic hazards. However, despite various government policies and international restrictions that recognized the severity of plastic pollution and microplastic hazards caused by traditional plastic, the traditional plastic industry, which has low production costs and a well-established industry structure, and consumers′ preference for cheap and convenient traditional plastic products pose a challenge to the development of the biodegradable plastic industry. The production cost of fossil-fuel-based traditional plastics has increased due to the need for environmental responsibility and related expenses. However, the acceptance of the biodegradable plastic industry by the consumer market is more crucial than government policies to drive future development.
Through the Structure-Conduct-Performance model analysis of the biodegradable plastic industry, it can be seen that in terms of industry structure (S), it is a relatively new and small industry with a few major players and some smaller companies. The industry′s characteristic is high capital investment because the production of biodegradable plastics requires significant investment in research and development, equipment, and facilities. In addition, the industry is constrained by strict environmental regulations, making it difficult for new companies to enter the market. Regarding firm behavior (C), the focus is usually on developing new products, improving manufacturing processes, and reducing costs. Companies engage in active marketing and promotional activities to establish brand awareness of their products. In terms of industry performance (P), biodegradable plastic industry companies′ performance is measured in various ways, including profitability, technological progress, and sustainable development. Profitability is influenced by factors such as cost structure, pricing strategy, and economies of scale. Technological progress is a primary concern for many companies in the industry, and they strive to minimize waste and pollution during the production process. Sustainable development is another important performance indicator because companies compete for customers based on product quality, price, and sustainability factors. Therefore, the biodegradable plastic industry is a complex and evolving industry type, and industry development is heavily influenced by government regulation and environmental factors. Companies within the industry must address these challenges while developing innovative products and processes to maintain market competitiveness. |
