焦作市产业结构变动与效益综合实证分析

Comprehensive Empirical Analysis on Industrial Structure Changes and Benefit of Jiaozuo

运用产业结构变化率、产业结构变动系数、比较劳动生产率及其差异指数,以及动态偏离—份额分析模型,对2003—2010年焦作市产业结构变动和效益进行了实证分析,结果显示:(1)焦作市产业结构整体变化较快,速度高于全省平均水平;但产业结构内部不平衡,第二产业增长相对较快,第一产业和第三产业增长相对缓慢。(2)第二产业劳动生产率高于产业平均水平和全省平均水平,产业优势明显。第一产业和第三产业劳动生产率持续下降,低于产业平均水平和全省水平,并导致整个产业结构效益由高于全省水平转变为低于全省水平。(3)从整体上看,焦作市三次产业都为增长性产业,增长高于全省平均水平,在产业结构和竞争力上都有一定优势。但从产业内部看,焦作市在产业结构和竞争力上的优势主要来源于第二产业,并且优势明显,抵消了第一产业和第三产业在产业结构和竞争力上的劣势。

Using the rate of industrial structure change, coefficient of industrial structure variation, com- parative labor productivity and its difference index as well as dynamic deviation-share analysis model, the author empirically analyzes industrial structure changes and benefit of Jiaozuo city from 2003 to 2012, the results show ： （ 1 ） The overall industrial structure of Jiaozuo City changes fast and is higher than the pro- vincial level; however, the interior of industrial structure is imbalanced, and the growth of secondary in- dustry is relatively fast, while the growth of primary industry and tertiary industry are relatively slow. （2） The labor productivity rate of secondary industry is higher than the average level of industry and the prov- ince with obvious advantages. The labor productivity rate of primary industry and tertiary industry is lower than the average level of industry and lead to the entire industry benefit transforms from the level higher than the province to the level lower than the province. （3） Overall, three industries of Jiaozuo city are growing and are higher than the provincial average level. However, from the interior of the industry, the advantages of industrial structure and competitiveness in Jiaozuo city come mainly from the secondary in-dustry, and its advantages are obvious, which offsets the disadvantages of industrial structure and compet- itiveness of primary industry and tertiary industry.
