区域要素禀赋结构变动对农产品价格的影响研究——基于苹果产区要素禀赋与价格相关性分析

Research on the Impact of Regional Factor Endowment Structure Changes on Agricultural Product Prices——Based on the analysis of the correlation between factor endowments and prices in apple producing areas

各地立足区域要素禀赋资源优势,打造各具特色的农业全产业链,调整优化农业结构,对农民增收、农产品市场稳定及国民经济高效循环具有重要意义。本文以2003-2018年21个省级面板数据为研究样本,构建要素禀赋指数,设置邻接空间、地理距离、经济空间三种权重矩阵,并利用空间回归模型偏微分方法进行实证分析。结果表明:我国各苹果产区要素禀赋结构存在较大差异,但总体逐步向现代农业要素构成方向优化;在不同的空间矩阵模式下,各区域苹果集贸市场价格具有显著的空间依赖性和空间异质性——土地、资本、技术要素对苹果集贸市场价格存在负向抑制作用,劳动力要素对苹果集贸市场价格存在正向带动作用;受农产品市场自身封闭性的影响,经济因素对苹果集贸市场价格的空间作用不明显。

Based on regional factor endowments and resources’ advantages, all localities will create a full agricultural industry chain with their characteristics and adjust and optimize the agricultural structure. These are of great significance to the increase of farmers’ income, the stability of the agricultural product market, and the national economy’s efficient circulation. This paper uses 21 provincial panel data from 2003 to 2018 as the research sample, constructs the factor endowment index, sets up three weight matrices of adjacent space, geographic distance, and economic space, and uses the spatial regression model partial differential method to conduct empirical analysis. The results show that there are significant differences in the factor endowment structure of various apple-producing regions, but the overall structure of modern agricultural factors is gradually optimized;under different spatial matrix models, the price of apple market markets in each region has significant spatial dependence and space.Heterogeneity-land, capital and technological factors have a negative inhibitory effect on apple fairs’ price. Labor factors have a positive driving effect on apple fairs’ prices;affected by the closed nature of the agricultural product market, economic factors have an impact on apples. The spatial effect of market prices is not obvious.
