中国海外耕地投资规模与地缘经济的耦合协调研究

Research on the coupling coordination between the scale of China's overseas farmland investment and geo-economy

探究中国海外耕地投资规模与地缘经济耦合协调的空间分异及驱动因素有助于为中国企业科学开展海外耕地投资活动提供参考。本文构建中国海外耕地投资规模及地缘经济的评价体系,借鉴耦合协调模型测算二者耦合协调度,并对其空间分异特征和驱动因素进行分析。结果表明:①中国海外耕地投资规模及中国与各东道国的地缘经济联系呈高度分散化,投资规模较好、地缘经济较密切的地区位于俄罗斯和东南亚。②投资规模与地缘经济耦合协调度呈显著正相关,局部地区已形成明显的空间分化,高高集聚区分布于东南亚。③耦合协调发展受营商便利指数、国内生产总值、人均淡水资源拥有量、谷物单产、百万人互联网拥有量和法律权利力度指数6个因子的显著影响。④以上6个因子对耦合协调发展的影响具有空间差异和增强型交互作用,其中国内生产总值与任意因子作用时产生的增强效应值均较为明显。应从优化海外耕地投资及地缘经济发展的空间格局、探索区域差异化路径、完善规划及关注耦合协调提升的影响因素方面提升二者的耦合协调发展。

Exploring the spatial differentiation and driving factors of the coupling coordination between the scale of China's overseas farmland investment and geo-economy can provide a reference for Chinese enterprises to scientifically implement overseas farmland investment activities.This paper establishes a system to evaluate China's overseas farmland investment scale and geo-economy,measure the degree of coupling coordination between the two using the coupling coordination model,and analyze the spatial differentiation characteristics and driving factors.The results show that:(1)The scale of China's overseas farmland investment and the geo-economic ties between China and each host country are highly decentralized,with the regions having a higher investment scale and closer geo-economy located in Russia and Southeast Asia.(2)The coupling coordination degree of investment scale and geo-economy is significantly and positively correlated,and strong spatial differentiation has been observed in certain localities.The high-high agglomeration is distributed in Southeast Asia.(3)The coupling coordinated development is heavily influenced by six factors,including the ease of doing business index,GDP,per capita freshwater resource ownership,cereal yield,internet ownership of millions of people and legal rights strength index.(4)The effects of six factors,namely the ease of doing business index,GDP,per capita freshwater resource ownership,cereal yield,internet ownership of millions of people and legal rights strength index,has spatial differences and enhanced interaction effects.Among them,the enhancement effect value produced by GDP and any factor is more obvious.The following four aspects should be considered to strengthen the coupling coordination development of overseas farmland investment and geo-economy:optimizing the spatial pattern between the two,exploring regional differentiation paths,improving strategic planning and considering the factors influencing the promotion of the coupling coordination.
