基于跨区域全面深化合作的战略行动需要，从粮食经济的微观主体、中观产业和区域总体等多维度构建区域粮食经济高质量发展的系统框架与评价指标体系，选择空间关联且具有典型市场与资源禀赋差异的湘粤两省进行测度分析。研究结果表明：湘粤两省粮食经济高质量发展均处于系统测试的低水平阶段，区域粮食经济的三维行为具有市场高效率竞争和高能量释放的潜质特征；市场经济体制下粮食经济系统“三维”主体行为对粮食经济高质量发展具有不同的影响；湘粤两省粮食经济高质量发展既具有区域行为的趋同性，也有区域行为的差异性，表明湘粤两省具有粮食经济高质量发展的互补性合作空间。因此，要实现跨区域粮食经济高质量发展必须加强跨区域市场主体行为竞争，拓展粮食产业的区域合作空间，推进跨区域粮食全产业链建设，增强跨区域系统结构行为协同。

Based on the need for strategic action to comprehensively deepen across-regional cooperation, a system framework and evaluation index system for the high-quality development of the regional food economy have been constructed from multi-dimensions such as the micro-main body of grain economy, the middle industry and the region as a whole, with Hunan and Guangdong provinces selected as measure objects because of their spatial correlation, their typical markets and resource endowment differences. The results show that the high-quality development of the grain economy in both Hunan and Guangdong provinces is still at the primary stage of the system test, and the three-dimensional behavior of the regional grain economy is characterized by the potential for efficient market competition and high energy release; under the market economy system, the behavior of the three-dimensional objects of grain economy system has different effects on the high-quality development of grain economy; the high-quality development of grain economy in Hunan and Guangdong provinces has both the convergence of regional behavior and the difference of regional behavior, which shows there is scope for complementary cooperation between the two provinces in terms of quality food economic development. Therefore, in order to achieve cross-regional high-quality development of the grain economy, it is necessary to strengthen cross-regional competition in the behavior of market players, expand the space for regional cooperation in the grain industry, promote cross-regional construction of the cross-regional grain industry chain, and enhance the behavior coordination of the cross-regional system structure.
