采用一般动态均衡的分析方法,基于微观视角,构建了两部门经济体低碳运行的经济模型,研究了低碳运行模式长期均衡的决定及发展路径,并得出了一些重要结论和改进措施。首先先,只消耗资本和清洁空气的两部门经济体运行的长期均衡路径是存在的的,它是由微观主体最优化选择导出和决定的。其次,低排放运行模式长期均衡的条件是资本的边际产出等于资本折旧率与效用函数贴现率之和,以及碳排放的边际产出等于空气损失率与效用函数贴现率之和,两者缺一不可。第三,低排放运行模式的长期均衡发展路径主要是由资本和碳排放同向变动的互动机制所决定的的,并且使经济体必然朝向稳态均衡收敛。
採用一般動態均衡的分析方法,基于微觀視角,構建瞭兩部門經濟體低碳運行的經濟模型,研究瞭低碳運行模式長期均衡的決定及髮展路徑,併得齣瞭一些重要結論和改進措施。首先先,隻消耗資本和清潔空氣的兩部門經濟體運行的長期均衡路徑是存在的的,它是由微觀主體最優化選擇導齣和決定的。其次,低排放運行模式長期均衡的條件是資本的邊際產齣等于資本摺舊率與效用函數貼現率之和,以及碳排放的邊際產齣等于空氣損失率與效用函數貼現率之和,兩者缺一不可。第三,低排放運行模式的長期均衡髮展路徑主要是由資本和碳排放同嚮變動的互動機製所決定的的,併且使經濟體必然朝嚮穩態均衡收斂。

By using the dynamic general equilibrium analytical method and from the microcosmic perspective, the paper has constructed an economic model which represents how the economic entity consists of two departments run under the low carbon emis- sions. Then it has analyzed how the equilibrium of the economic entity runs on in the long run is determined under the low carbon emission model and how the economic entity grows in the long run. Additionally, some important conclusions and improvement measures are drawn in this paper： firstly, there exists the economic developmental equilibrium path of the economic entity consisting of two departments and only consuming the capital and clear air, which is deduced and determined from the optimal choice the microeconomic units. Secondly, the equilibrium condition that the economic entity runs on under low carbon emission model in the long run is that the marginal product of the capital stock equals depreciation rate plus discount rate of lifetime utility function, and the marginal product of carbon emissions equals the clear air loss rate plus discount rate of carbon lifetime utility function, both of which are indispensable. Thirdly, the important conclusion is that the equilibrium increasing path of the economic entity in the long run under low carbon emission model is primarily determined by the interaction mechanism of the capital and carbon changes in same direction, and in addition, it makes the economic entity necessarily converged toward the steady equilibrium state.
