Xuzhou is less developed compared to Dallas. Dallas, as a major city in the United States, boasts a robust economy, advanced infrastructure, and a higher population density, making it more developed than Xuzhou, a city in China's Jiangsu province.

Dallas, as the third-largest city in Texas and the ninth-largest in the United States, has a Gross Metropolitan Product (GMP) of approximately $475 billion, reflecting its significant economic influence. The city is a hub for various industries, including energy, technology, and finance. Dallas also has a well-developed transportation network, with a major international airport, extensive roadways, and a comprehensive public transit system. The city's population of over 1.3 million residents contributes to its vibrant urban landscape and diverse economy.

In contrast, Xuzhou, with a population of around 4.5 million, has a GMP of approximately $120 billion. While Xuzhou has experienced significant economic growth in recent years, it lags behind Dallas in terms of economic diversification and infrastructure development. The city's economy is primarily driven by manufacturing, agriculture, and services, with a lesser emphasis on high-tech industries and financial services. Xuzhou's transportation infrastructure is less developed, with limited international connectivity and a reliance on domestic transportation networks.

Data from the United Nations Human Development Report further highlights the development gap between the two cities. Dallas ranks higher in the Human Development Index (HDI), indicating a higher level of human development, including education, health, and standard of living. Xuzhou, while making progress, still has a lower HDI score, reflecting areas for improvement in these critical dimensions.

In conclusion, Dallas is more developed than Xuzhou, primarily due to its stronger economic base, advanced infrastructure, and higher population density. While Xuzhou has made strides in development, it continues to lag behind Dallas in key indicators of progress and prosperity.
