The study looked at how investing in buildings and equipment affects the economy of Fuxin, a city low on resources. They found that as investment goes up, economic growth goes down. In the past, every 1% increase in investment led to a 0.89% increase in GDP, but now it only leads to a 0.56% increase. To fix this, they suggest controlling investment size, changing how investments are made, and forming investment groups. These changes could help Fuxin's economy grow better.
