基于隐含碳基础计算了广东省2000—2012年14个制造业的环境贸易条件(PTT,衡量一个国家或行业在贸易中比较优势的指标)。结果表明,广东省2012年制造业的PTT较2000年整体提升51%,其中食品制造加工业及纺织业是所有部门中PTT最优的,石油加工、炼焦及核燃料部门的PTT相对较差。同时,利用聚类标准误检验,得出企业规模、人均劳动报酬的增加以及滞后固定资产的更新会优化环境贸易条件,而能源强度和全员劳动生产率的增加会恶化环境贸易条件。
Based on the implicit carbon basis, the environmental trade conditions (PTTs) of 14 manufacturing industries in Guangdong Province during 2000-2012 were calculated to measure the comparative advantage of a country or industry in trade. The results show that PTT of manufacturing industry in Guangdong province increased by 51% as compared with 2000 as a whole, with PTT being the best in all sectors in the food manufacturing and processing industry and the textile industry in PTT in the petroleum processing, coking and nuclear fuel sectors being relatively poor. At the same time, we use cluster standard error test to conclude that the increase of enterprise size, per capita labor remuneration and the lag behind of fixed assets will optimize the environmental trade conditions. However, the increase of energy intensity and total labor productivity will aggravate the environmental trade conditions.
