In China, making the most of urban green spaces is crucial for sustainable growth. To figure out how economic goals affect these green areas, a study looked at 273 cities from 2010 to 2021. This study used different models to see how strict or flexible economic targets impact green land use.

The findings were clear. Hard economic targets, like strict growth goals, often lead to less green space. This is because cities might focus more on building and less on preserving parks and green areas. However, when cities have softer, more flexible goals, they tend to use their green spaces more efficiently. This is likely because they can balance growth with environmental needs.

The study also found that green technology and upgrading industries play a big role in how well cities use their green spaces. As cities invest in green tech and modernize their industries, they can grow without sacrificing their parks and green areas.

Environmental rules also make a difference. As these rules get stricter, the negative effects of hard economic goals on green spaces lessen. This means that even if a city has strict growth targets, strong environmental rules can help protect green spaces.

Interestingly, the economic goals of neighboring cities can also affect a city's green spaces. If nearby cities have hard economic targets, it can reduce green spaces in a city. But if they have softer targets, it can improve green spaces.

The study also showed that certain regions and types of cities are more affected. Central regions and cities that rely on resources like mining or logging see the biggest negative impact from economic growth targets on their green spaces.

So, what's the takeaway? Cities should focus less on GDP growth when evaluating performance. Instead, they should use more flexible "soft constraints" to set economic goals. This way, they can grow economically while still keeping their green spaces green.
