The reason why Changshu Dongbang is not developed is mainly due to the following reasons:

1. The geographical location is relatively remote: Changshu Dongbang is located in a relatively remote area in Changshu City with less people flow, so it lacks geographical advantages for development. The inconvenient transportation also limits its economic exchanges and cooperation with the outside world.

2. Low level of economic development: Due to the geographical restrictions, the economy of Changshu Dongbang is relatively backward, and the investment enthusiasm is weak. This makes it face great difficulties in attracting investment, upgrading technology and introducing talents, which limits its development.

generally speaking, the development of Changshu Dongbang is restricted by geographical and economic factors. However, with the improvement of the overall economy of Changshu, I believe that Changshu Dongbang will gradually get rid of these constraints and move towards better development.
