Five major industrial clusters in Guangzhou, including textile and clothing, beauty and daily chemical, luggage and leather goods, jewelry, and food and beverage, are selected to analyze the evolution trend of the composite system between digital trade and industrial clusters. The study found that the luggage and leather goods industry is in the expansion stage of the synergy between digital trade and industrial clusters. The other four industries are still in the initial stage of digital trade and industrial cluster synergy, with low synergy level. The textile clothing industry has the least obvious growth momentum, showing the lowest level of synergy between digital trade and industrial clusters. By promoting the efficient evolution of the system, the upgrading and transformation of industrial clusters through digital trade can be achieved, and the deepening development of digital service trade based on industrial clusters can be effectively supported. This paper can provide recommendation for the collaborative development of Guangzhou's industrial digitization and digital industrialization.

Leveraging data from the 2020 mainland China and Taiwan Agricultural Statistical Report, we constructed a model to analyze the impact of mainland China's trade policy changes on the pineapple market in Taiwan. The results of the analysis indicate that the policy change will have a severe impact on Taiwan's pineapple market and will significantly affect producers' investment confidence. Achieving market equilibrium and overall efficiency in the pineapple market would be challenging, given the targeted nature of this policy change. Comparatively, the fruit industry, including pineapples, exhibits the weakest durability in risk management against such targeted policy changes, when compared to other agricultural products. Import policies from large unified market economies have a decisive impact on small exporting regions.
