This milestone signifies that China’s manufacturing industry has entered a comprehensive acceleration phase of digitalization. It is of a great importance for Jiangxi Province to clarify the key aspects, development trends, and supply capacity of the industrial internet industry chain. This is crucial for promoting the construction of the “Number One Development Project” for digital economy, as it supports the transformation and upgrading of Jiangxi’s manufacturing industry and drives high-quality development. After analyzing the background and current situation of the industrial internet industry, this report breaks down the integrated solutions in relevant industrial internet cases.
