Design of Intelligent Environment Observation and Decision Support for Regional World Economy

In order to avoid the risk of marginalization of low-level areas in the process of economic globalization, regional economies have also developed from this, which is important for the regional world economy in a smart environment. Observation and decision support have also attracted much attention from academia. Based on the important situation of regional world economic development, scholars have conducted a lot of research studies; this paper studies the development trend of the regionalized world economy in the intelligent environment under the network of interconnected objects and uses decision support technology and sensor networks to observe and design decision support for the regionalized world economy. Association rule mining technology is used to conduct data mining and data collection on the relevant data in the regionalized world economy, cluster analysis is used to sort and calculate the mined experimental data, and the experimental data model is extracted through the decision tree algorithm. This study collects various data on the number of trade agreements in 2015–2019, the expansion of free trade zones, the import and export trade rates of the EU, North America, and the Asia-Pacific region, and the currency circulation in each region of the world and also organize, observe, and analyze the regional world economy. The final results show that, from 2015 to 2019, free trade areas in various regions of the world are expanding every year. There are 12 free trade areas in Western Europe, the Middle East, the Mediterranean, Central and Eastern Europe, and Russia. At the same time, North America, Asia-Pacific, and the EU pay more attention to intraregional trade, especially the annual trade rate of the EU of more than 50%. The regional world economy still has a trend of development in modern society and even in the next few decades, and the regional world economy has a certain role in promoting the economic development of various countries and regions. The regional world economy still has a development trend in modern society and even in the next few decades. It has a certain promoting effect on the economic development of various countries and regions. It is an inevitable trend of world economic development and the only way to economic globalization.
