中国各省份城镇家庭耐用品物质存量分析

Stock Material Metabolism of Urban Household Durable Goods in China’s Provinces

摘要: 本文对我国31个省份2014年城镇家庭耐用品消费的材料存量进行了代谢分析，量化了家庭耐用品消费的物质代谢结构与格局。研究结果表明：2014年，中国城镇家庭耐用品存量总量达到13,087.37万吨，输入量、输入量分别为8012.79万吨和5795.73万吨。各省城镇家庭的耐用品物质流量及存量呈现东部沿海地区高，西部内陆地区低的特点，并与各省的GDP有较高的复合关系，而净存量增加量则由于经济体量与人口数量的差异，呈现出不规则的分布。同时，东部地区在户均存量及流量上普遍高于西部地区，但相对差距并不显著，净存量增加量相差更小，西部地区普遍略高。

Abstract: In this paper, the consumption of urban household durable goods in China’s 31 provinces is used to quantify its structure and pattern in material stock and flow in 2014. The results show that in 2014, the total stock of urban households durable goods in China reached 13,087.37 million tons, and the input and input amounted to 8012.79 million tons and 5795.73 million tons respectively. The flow and stock of durable goods in urban households in all provinces are high in the eastern coastal areas and low in rest areas. Besides, it has a higher composite relationship with the GDP of the provinces. The increase in net stock is due to the difference between the economy and the population, showing an irregular distribution. At the same time, the average stock and flow per capita in the eastern region are generally higher than those in the western region, but the relative gap is not significant, and the difference between the net stock increases is even smaller and the western region is generally slightly higher.
