黑龙江省数字经济与农业绿色发展的耦合协调及区域差异分析

Analysis on the Coupling Coordination and Regional Differences between Digital Economy and Green Agricultural Development in Heilongjiang Province

摘要:

数字经济与农业绿色发展的良性互动、协同共进是实现农业高质量发展的重要推动力。为探究黑龙江省数字经济和农业绿色发展的耦合协调情况，选取2014—2023年黑龙江省及13个地级市的面板数据为样本，采用耦合协调模型与Dagum基尼系数等方法分析二者耦合协调度的时空变化特征及区域差异来源。结果表明，黑龙江省数字经济与农业绿色发展除哈尔滨外均处于较低水平，增长速度缓慢，耦合协调度总体呈现波动式上升趋势，但并未达到高质量协调发展状态。区域差异的主要来源由超变密度变为组间差异，西部核心区与东北部外围地区差距扩大。因此，应针对区域差异因地制宜施策，充分发挥各区域优势加强合作，坚持人才培养与技术研发创新，让数字经济与农业绿色发展能够协同发力、相互促进，以此推动黑龙江省实现农业高质量发展。

Abstract:

The positive interaction and coordinated advancement between the digital economy and green agricultural development are important driving forces for achieving high-quality agricultural development. To explore the coupling and coordination between the digital economy and green agricultural development in Heilongjiang Province, panel data from 2014 to 2023 for Heilongjiang Province and its 13 prefecture-level cities were selected as samples. The coupling coordination model and methods such as the Dagum Gini coefficient were used to analyze the spatiotemporal variation characteristics and sources of regional differences in the degree of their coupling and coordination. The results show that except for Harbin, both the digital economy and green agricultural development in Heilongjiang Province are at relatively low levels and grow slowly. Overall, the degree of coupling and coordination shows a fluctuating upward trend but has not reached a state of high-quality coordinated development. The main source of regional differences has shifted from hyper-variance density to inter-group differences,with the gap between the western core area and the northeastern peripheral areas widening. Therefore, policies should be tailored to regional differences, fully leveraging the advantages of each region to strengthen cooperation, persist in talent cultivation, technological R&D and innovation, so that the digital economy and green agricultural development can work in synergy and promote each other to drive the high-quality development of agriculture in Heilongjiang Province.
