分行业技术进步的测度:基于投入产出表和校准法的分析

The Measurement of the Technical Progress in the Sector Scale:An Analysis Based on the Input-output Table and Calibration Method

技术进步的测度是发展经济学长久以来持续关注的问题,发展中国家的技术进步率尤其为经济学者所关注,因为这关系到发展中国家经济是否可持续的问题。对于中国的技术进步,已有的研究多以国家或者省区为尺度。本文以中国1987-2007年投入产出表的数据为基础,使用经典的柯布-道格拉斯函数,通过校准法测算了中国17行业的技术进步。测算结果表明:在17个行业中,采掘业的技术进步最快,达到了6.19%;炼焦、煤气及石油加工业,金融保险业,农林牧副渔业的技术进步率也在4%以上;建筑材料及其他非金属矿物制品业,其他制造业,商业饮食业,运输邮电业,建筑业,机械设备制造业,纺织、缝纫及皮革产品制造业的技术进步也达到了3%;其他服务业则进步缓慢,仅有1.13%。更有甚者,食品制造业,电力及蒸汽、热水生产和供应业则存在某种程度的下降。

The measurement of the technical progress is one of the key issues in the development economy for a long time. The economists have paid much attention to the technical progress in the developing countries because of its close relationship with the sustainable development of the developing countries. So far as to the study of technical progress in China,many scholars have calculated it in the scale of nation or province. In this paper,we calculate the technical progress in the sector scale base on the Input-output table（ 1987-2007） and the Cobb-Douglas production,combined with the calibration method. The results show that technical progress of the mining sector is the highest,namely 6.19%. The technical progress of coking,gas and processing of petroleum,the finance and insurance,and the agriculture,forestry,animal husbandry fishery sectors are also more than 4%. And the technical progress of the manufacture of nonmetallic mineral products,other manufacture,commercial and catering service,transportation and postal,construction,machinery and equipment,and textile,sewing,leather and furs products sectors are also almost 3%. However,the technical progress of other service sector is only 1.13%. What＇s worse,the technical progress of the food stuff,production and supply of electric sectors are even less than 0.
