区域经济综合外向度的多维测度方法及实证研究

Multidimensional Measurement and Empirical Research on Comprehensive Extraversion of Regional Economy

在"一带一路"倡议及区域经济深度融入沿线经济带的背景下,探索区域经济外向度的测度方法和影响因素。首先从外贸、外资、外经3个角度构建区域经济外向度的多维测评指标体系,应用主成分分析法对区域经济综合外向度加以测评;然后从区域经济发展水平、产业结构、贸易结构、汇率、资源禀赋等5个维度构建区域经济综合外向度影响指标体系,应用灰色关联模型对各因素影响程度进行测度;最后以河南省的经济数据为依托进行实证研究,验证了区域经济综合外向度的多维测度方法的可行性。

Under the background of ＂the Belt and Road＂ initiative and the deep integration of regional economy into the economic belt along the route, the paper explores the measuring methods and influencing factors of regional economic extroversion. Firstly, the multi-dimensional evaluation index system of regional economic extroversion is constructed from three angles of foreign trade, foreign capital and foreign economy, and the comprehensive extroversion of regional economy is evaluated by principal component analysis. Secondly, the multi-dimensional evaluation index system of regional economic extroversion is constructed from five angles of the level of regional economic development, the industrial structure, trade structure, exchange rate, and resource endowment, using the gray rela- tional model to measure the degree of influence of each factor. Finally, based on the economic data of Henan Province, empirical researches are carried out to verify the feasibility of multidimensional measurement method of regional economic comprehensive extraversion.
