中国地区专业化水平的测度:基于省际数据的研究

Measurement of China's Regional Specialization Based on Provincial Data

经济增长的解释离不开对专业化分工水平的研究,研究方法的合理性直接关系到研究结论的准确性。选择地区专业化系数对我国1997—2011年地区专业化水平的研究表明,从地区角度来看,我国东部地区专业化水平在持续提升之后,受制度等因素的影响,2006年开始出现下降;中西部地区专业化水平则因资源密集型产业的制约难以提高。从行业角度来看,代表高新技术的电子及通信设备制造业专业化水平一直处于最高,成为国民经济的支柱产业,但高能耗、高污染的黑色金属冶炼及压延加工业、纺织业依然占有重要的地位。

Interpreting economic growth depends on solid researches on the level of specialization, and good approaches often decide the validity of research findings. This paper measures China＇s industrial regional specialization level from 1997 to 2011 by using the regional specialization coefficient. Looking from a regional perspective, East China had witnessed a steady rise of the level of specialization before 2006, when it began to decline; Central and West China, restricted by its dependence on resource-intense industries, is facing a difficult time in raising its level of specialization. In terms of industries, electronics and telecommunication equipment manufacturing have maintained the highest level of specialization, while energy-consuming and heavily polluting industries such as ferrous metallurgy and textiles still have an important role in the national economy.
