Western cities in China are experiencing rapid and steady economic growth. Researchers measured this growth using per capita budgetary income and per capita GDP as indicators. They found that higher per capita GDP contributes positively to economic development, while the growth rate of per capita budgetary income is also a good sign. However, the growth rate of per capita GDP needs further analysis. Different cities have varying levels of economic development, with larger cities benefiting from scale economies in public services, and medium-sized cities focusing on dominant industries. Lower-developed cities may need to adjust their growth strategies and receive public policy support.
