基于数据包络方法(DEA)的Malmquist生产率指数对1999—2007年天津滨海新区工业技术进步、效率变动及全要素生产率(TFP)变化作了测度。分析表明:新区工业全要素生产率增长迅速,这主要得益于技术进步,而技术效率却有所下降;2002年之后技术进步速度加快,技术效率则进一步恶化。七大支柱产业中有六个产业的全要素生产率提高,位居工业各行业前列;外资企业处于技术前沿,集体和私有企业成为推动全要素生产率提升的重要力量,但国有企业和港澳台企业的技术水平不高,在各所有制经济技术水平不断提升条件下依旧处于水平较低状态。
The Malmquist productivity index based on data envelopment (DEA) measures the changes of industrial technology, efficiency and total factor productivity (TFP) in Tianjin Binhai New Area from 1999 to 2007. The analysis shows that the total factor productivity of the new district is growing rapidly, mainly due to technological progress, while the technical efficiency is declining. Since 2002, the technological progress has accelerated and the technical efficiency has further deteriorated. The total factor productivity of six industries in the seven pillar industries has risen to the forefront of all industries; while foreign-funded enterprises are at the forefront of technology, collective and private-owned enterprises have become the major force in promoting the enhancement of total factor productivity. However, the state-owned enterprises, Hong Kong, The technical level is not high, and the economic and technological level in all ownership systems is still at a low level under the conditions of continuous improvement.
