Agriculture is a large source of carbon emissions. The cropland practices of fertilizer substitution, crop straw and conservation tillage are beneficial and help to rebuild local soil carbon stocks and reduce soil carbon emissions, in addition to reducing the consumption of fertilizers and fossil fuels. These improved cropland practices can directly and indirectly mitigatecarbon emissions, benefiting the sustainability of croplands. For these three improved practices, we estimated carbon mitigation potentials in rice, wheat and maize croplands in China. The combined contribution of these practices to carbon mitigation was 38.8 Tg C yr-1, with fertilizer substitution, crop straw return, and conservation tillage contributing 26.6, 3.6 and 8.6 Tg C yr-1, respectively. Rice, wheat and maize croplands had potentials to mitigate 13.4, 11.9 and 15.5 Tg C yr-1, respectively, with the combined direct and indirectpotential of 33.8 and 5.0 Tg C yr-1. Because of differences in local climate and specific diets, the regional cropland carbon mitigation potentials differed greatly among provinces in China. In China, 18 provinces had a "target surplus" for which the carbon mitigation from these three practices was larger than the mitigation target set for 2020. At the national level, a net "target surplus"of 4.84 Tg C yr-1 would be attained for Chinese croplands with full implementation of the three improved practices. regional cooperation must be developed to achieve carbon mitigation targets using such measures as carbon trading, establishing regional associations, and strengthening research programs to improve practices.

本文针对长三角绿色发展过程中的区域合作问题，全面梳理了相关的文献，归纳了区域合作相关理论，从“要素”视角出发，提出了绿色发展区域合作的理论框架。研究认为，“要素”特征是驱动绿色发展区域合作的重要因素，不同特征对于绿色发展区域合作的影响不同。同时，基于长三角区域一体化中的绿色发展实践，结合要素的异质性和替代性两个角度探索实现区域绿色发展的政策选择，提出“十四五”期间优化长三角绿色发展区域合作的对策建议。

泛珠三角区域合作十多年来从概念构想、制度安排到机制设计，取得了显著的成效。透过威廉姆森制度演化的四个层次分析框架及其相互关系，可发现泛珠三角区域合作的制度演化中在第一层次的非正式制度方面泛珠三角区域各具特色但交融影响；宪法和法律等第二层次的制度为其合作提供了基本的制度环境；第三层次的日趋完善治理机制有效推进了泛珠三角的区域治理；而作为资源配置机制使各个领域的合作取得实质性的进展，且不同层次之间的制度演化互动明显，形成区域合作的制度体系。未来推进区域合作的深入在嵌入性制度层面需要加强民间的交流与融合，在制度环境方面要融入国家区域发展战略和加强区域合作的法制建设，在治理机制方面要健全合作架构和完善省际合作机制，在资源配置方面要制定泛珠三角区域合作的规划、实施和评估方案。
