基于三角形中线的三次产业结构变迁路径研究

A Study on the Tertiary Industrial Structure Evolution Route Based on the Triangle Median

本文在前人研究的基础上,利用三角形中线对三次产业结构变化的六种形式及其内部关系进行了深入研究,结果表明六种形式之间的变化路径,各种形式之间可能发生转化,一定是渐进的,不能跨越;每一种形式的数学约束,可以用一组不等式表示;用三角形的三条中线来划分三次产业结构的六种形式,在三角形中能简洁有效的表示这六种形式及其变化。提出了顺时针优化发展路径和逆时针优化发展路径。对一段时期中国、美国、日本、老挝等国家三次产业结构的变迁进行了简洁有效的描述。

Based on studies of other scholars, this paper studies the six forms of changes of the tertiary industrial structure and their internal relations by making use of the triangle median. The study demon- strates the evolution routes of these six forms and shows that they are interchangeable, progressive and can- not be bypassed. The mathematical constraint of each form can be expressed in a set of inequations. The three medians of the triangle can be used to classify the six forms of the tertiary industrial structures and their changes in an effective and concise manner. The paper suggests that the development routes can be optimized both CW and CCW. The paper also concisely describes the evolution of the tertiary industrial structures of China, USA, Japan, Laps and other countr/es.
