Manufacturing GDP includes the economic value created in the whole process of manufacturing production, reflecting the contribution of manufacturing to the economic growth of a country or region.

The growth rate of manufacturing GDP is an important indicator to measure the production capacity and competitiveness of the manufacturing industry. A high growth rate usually indicates that the country or region's manufacturing capacity and competitiveness have improved, and it can achieve a greater share of the global market. The high growth rate of the manufacturing industry can also drive the development of other industries and promote the economic growth of the country or region.

It should be noted that with the deepening of economic globalization and industrial division of labor, the proportion of manufacturing GDP in the national or regional economy is changing. The manufacturing industry in some developed countries or regions is transferring to developing countries or regions, resulting in a gradual decline in the proportion of their manufacturing GDP. At the same time, the continuous emergence of emerging technologies and business models is also changing the pattern and methods of manufacturing, further affecting changes in manufacturing GDP. Therefore, when formulating policies and planning development directions, it is necessary to fully consider these changes and take corresponding measures to promote the sustainable development of the manufacturing industry.
