摘要(Abstract):

统筹海陆发展,缩小海陆经济差异是海陆一体化建设的必然要求。按照海陆相对位置,将我国大陆各省市划分为四个梯度;基于区域经济梯度理论,运用区位商经典模型,系统测算1997—2014年各梯度的区位商;构建公式对沿海第一梯度对海陆经济差异贡献率进行测算和分析,研究海洋在海陆经济梯度差异形成过程中的作用。结果表明,我国由海向陆的四个梯度间存在区位商差异,其中,沿海地区所处的第一梯度较其他梯度差异明显;沿海第一梯度对海陆经济差异的平均贡献率达到85.36%,且该梯度与其余三个梯度的差异呈现出逐步缩小的趋势。
An inevitable requirement of sea-landintegrated construction is to balancesealand development and narrow the difference of sea-land economy. According to the distance from the sea, the provinces and municipalities in our country are divided into four gradients. Based on the theory of regional economic gradient, the paper calculatesthe location quotient of each gradientin 1997-2014 byapplying the location quotient classic model.Based on the above, the paper constructs a formula to measure and analyze the contribution of the first gradient, and studies the role of sea in the forming process of sealand economic gradient difference. Results show that there are differences among four gradients, and the first gradient in coastal areas has significant differencecompared with other gradients. In addition, the average contribution rate of the first gradient is 85.36%,and the difference between the first gradient and othergradients is gradually narrowing.
