Yongzhou has a population of approximately 4.5 million, making it the largest city in Hunan. This population size contributes to a larger labor force and a more dynamic market for goods and services. In contrast, Xiangtan has a population of around 2.3 million, which is significantly smaller. The larger population in Yongzhou supports a more diverse economy and a higher level of urban infrastructure development.

In terms of industrial development, Yongzhou has a stronger presence in key sectors such as energy, manufacturing, and agriculture. The city is home to several large-scale industrial parks and has been designated as a national-level economic and technological development zone. This has attracted significant investment and has led to the growth of high-tech industries, including electronics and pharmaceuticals. Xiangtan, while also having a diverse industrial base, does not have the same level of industrial concentration or the same level of investment as Yongzhou.

The GDP per capita in Yongzhou is also higher than in Xiangtan. According to data from the National Bureau of Statistics, the GDP per capita in Yongzhou was approximately $12,000 in 2020, compared to $8,000 in Xiangtan. This indicates a higher standard of living and a more developed economy in Yongzhou.

Additionally, Yongzhou has a more extensive transportation network, including a high-speed railway station and an international airport, which facilitates trade and tourism. Xiangtan, while also having transportation infrastructure, does not have the same level of connectivity as Yongzhou.

In conclusion, Yongzhou is more developed than Xiangtan based on population size, industrial strength, GDP per capita, and transportation infrastructure. These factors contribute to a more vibrant and prosperous city compared to Xiangtan.
