经济发展、土地城市化与环境质量

摘要 在经济发展的不同阶段，土地城市化与环境质量之间呈现不同的关系。当经济发展处于初期阶段时，土地城市化以规模扩张为主，环境质量处于下降阶段，土地城市化率与环境质量的变化是反向的；当经济发展到高级阶段时，土地城市化以质量提高为主，环境质量需求提升，政府在环境保护方面加大投入，土地城市化率与环境质量的变化方向会呈现一致。目前，我国土地城市化率和环境质量的变化之间总体上呈现负向的关系，并处于由第一阶段向第二阶段过渡的时期。因此，政府应大力推动绿色城镇化建设，构建绿色生产方式，建立绿色城市发展体系；同时通过加强土地供给侧改革，支撑绿色城镇化建设。
Abstract： At different stages of economic development, the relationship between land urbanization and environmental quality is different. When the economy is at its primary stage, land urbanization depends on its scale expansion, and the environmental quality is in a declining trend. The change direction of land urbanization rate and environmental quality is reversed. When the economy goes to the advanced stage, land urbanization is based on quality improvement. While environmental quality demand is enhanced, the government invests more in environmental protection. So the change direction of land urbanization rate and environmental quality will be consistent. At the present stage of our country, the relationship between land urbanization rate and environmental quality is overall negative in the transition from stage I to stage Ⅱ. Therefore, the government should vigorously promote the construction of green urbanization, build green production mode, and establish a green urbanization development system. At the same time, the government should support green urbanization by strengthening the land supply side reform.
