人口、能源与经济三者之间相互联系、相互制约,构成复杂的社会经济系统。我们这里试图利用推导的平均数关系式、增长率关系式和弹性关系式分析研究这三者之间的关系及其发展变化规律。一、平均数关系及其变化规律人均能源消费系数A_t=E_t/P_t;国民经济能源消费系数B_t=E_t/Y_t;人均国民收入(或GNP)系数C_t=Y_t/P_t。其中E 为能源消费量,Y 为国民收入总额(或GNP),P 为总人口,t 表示年份(或时期)。则三者间的关系是:人均能源消费系数=国民经济能源消费系数×人均国民收入(或GNP)系数。写成公式为
Population, energy and economy are interconnected and mutually restrained, forming a complex social and economic system. Here we try to use the deduction of the average number of relations, growth rate and elastic relationship analysis of the relationship between the three and its development and changes in the law. First, the relationship between the average and its changes in per capita energy consumption coefficient A_t = E_t / P_t; national economic energy consumption coefficient B_t = E_t / Y_t; per capita national income (or GNP) coefficient C_t = Y_t / P_t. Where E is the energy consumption, Y is the gross national income (GNP), P is the total population, and t is the year (or period). The relationship between the three is: per capita energy consumption coefficient = national economic energy consumption coefficient × per capita national income (or GNP) coefficient. Write the formula as
