乡村振兴与科技创新耦合机制及协调效应——基于烟台市11县区的实证分析

Coupling Mechanism and Coordination Effect of Rural Revitalization and Science and Technology Innovation-An empirical analysis based on 11 counties and districts in Yantai city,Shandong province

科技创新是推动乡村振兴的关键动力。以山东省烟台市为研究对象,采用熵权-TOPSIS评价模型、耦合协调度模型与相对发展度模型,考察科技创新与乡村振兴的耦合机制和协调效应。结果表明:(1)从发展水平看,烟台市乡村振兴与科技创新综合水平整体向好,但区域发展不平衡问题突出。(2)从耦合协调看,烟台市乡村振兴系统与科技创新系统之间存在强相关关系,2014-2018年期间为勉强协调阶段,2019-2022年期间升格为初级协调阶段,呈现出“西北部高耦合,东南部低耦合”的空间分布格局,随时间推移区域间的耦合差异有收敛趋势。(3)从相对发展情况看,烟台市正处于科技创新水平轻度滞后于乡村振兴水平的发展阶段,但二者之间的差异有缩小趋势。

Science and technology innovation is a key driving force for rural revitalisation.Taking Yantai City in Shandong Province as the research object,the entropy weight-TOPSIS evaluation model,coupling coordi-nation degree model and relative development degree model are used to examine the coupling mechanism and coordination effect of science and technology innovation and rural revitalisation.The results show that:(1)from the perspective of development level,the comprehensive level of rural revitalisation and science and technology innovation in Yantai City is generally good,but the problem of regional development imbalance is prominent;(2)from the perspective of coupling coordination,there is a strong correlation between rural revitalisation system and science and technology innovation system in Yantai City,which is barely co-ordinated during the period of 2014-2018,and is upgraded to the primary coordination stage during the period of 2019-2022,showing a spatial distribution pattern of"high coupling in the north-westem part of the city and low coupling in the southeastern part of the city",and the coupling differences between regions have a tendency to converge over time;(3)in terms of relative development,Yantai is at a stage of devel-opment where the level of science and technology innovation is mildly lagging behind the level of rural revitalisation,but there is a tendency to narrow down for the difference between the two.
