Summary
Environmental regulation boosts infrastructure investment efficiency, but optimal levels are key. Moderate regulation aids efficiency and reduces spatial spillover, while strict regulation has adverse effects.
Area of Science:
- Economics
- Environmental Science
- Urban Planning
Background:
- Infrastructure investment is crucial for economic growth but faces efficiency and environmental challenges.
- Examining the interplay between environmental regulation and infrastructure investment efficiency is essential.
Purpose of the Study:
- To analyze the influence mechanism and spatial effects of environmental regulation on infrastructure investment efficiency.
- To investigate the relationship between environmental regulation intensity and infrastructure investment efficiency.
Main Methods:
- Entropy weight method to measure environmental regulation.
- Super-SBM model to assess infrastructure investment efficiency.
- Spatial Durbin model to analyze spatial effects and influence mechanisms.
Main Results:
- Both environmental regulation and infrastructure investment efficiency exhibit spatial agglomeration.
- Environmental regulation generally promotes infrastructure investment efficiency with an inverted U-shaped relationship.
- Spillover effects of environmental regulation on infrastructure investment efficiency show a U-shaped pattern.
Conclusions:
- China saw increases in both environmental regulation and infrastructure investment efficiency from 2008 to 2020.
- Moderate environmental regulation benefits infrastructure investment efficiency and spatial spillover.
- Strict environmental regulation negatively impacts efficiency and spatial spillover, necessitating policy adjustments.

84
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

In the past, planning projects such as schools or public facilities required extensive manual effort to gather and compile data. Information such as property boundaries, soil characteristics, road networks, zoning regulations, and flood zones had to be sourced individually from courthouses, utility providers, and registry offices. Assembling these datasets into a coherent format often took several months, delaying project timelines.The introduction of Geographic Information Systems (GIS)...
