中国经济技术开发区效率测度及时空分异研究

运用数据包络分析法（DEA）及Malmquist生产率指数法,选择实际利用外资额、进口总额作为输入指标与GDP、出口总额作为输出指标,测算了中国41个国家级经济技术开发区2001~2010年的综合效率与全要素生产率指数,并对其时空分异特征进行分析。研究结果表明：① 平均综合效率偏低,总体呈“M”型变化趋势;② 综合效率区域差异明显,西部最高,东部次之,中部最低;③ TFP年均增长率为1.025,处于低速增长状态,说明开发区的整体生产效率逐年改善;④ TFP增长率地区分布为东部最高,西部次之,中部最低,综合效率较高的开发区TFP增长率反而较低;⑤ 对GDP增长速度与TFP增长速度双低的开发区进行分类指导与合理整治,以全面提高开发区的可持续发展能力。

Efficiency Measurement and Spatio-temporal Differentiation of Economic and Technological Development Zones in China

Economic and Technological Development Zones are the growth pole of China’s urban economic development. Therefore the study of the development efficiency of these zones is very essential to optimize resource allocations, to promote the transformation and upgrading of Economic and Technological Development Zones and to contribute to a sustainable development. Using the Data Envelopment Analysis (DEA) and Malmquist index, this article uses the total amount of foreign capital actually utilized and total import volume as input indicators, GDP and the total export volume as output indicators to calculate. the overall efficiency and total-factor productivity (TFP) index of China’s 41 state-level Economic-Technological Development Zones, from 2001 to 2010, are and analyzed their spatio temporal differentiation. The results suggest: 1) the average overall efficiency is generally on the low level, with an “M” trend. 2) Overall-development efficiency has an obvious regional differentiation with the highest in the west, and the lowest in the central regions. 3)The average annual growth rate of TFP is 1.025, which suggests that the overall production efficiency is ameliorating annually with a slow rate. 4) The growth rate of TFP is the highest in the east, and the lowest in central regions. The Zones with higher overall efficiency have relatively lower TFP growth rate. 5) In order to raise the sustainable development capacity of the development zones, we should offer respective guidance and reasonable regulation to zones with both low GDP growth rate and low TFP growth rate. Therefore, in order to strengthen the ability of resource allocation and integrated management, as well as to promote the transformation and upgrading of Economic and Technological Development Zones and sustainable development, we suggest as follows: 1) investment in human capital and innovation platforms should be increased and contributions of technological innovations be augmented to the overall efficiency of these zones, 2) the eastern region should gradually reduce their Economic and Technological Development Zones’ reliance on foreign capital and importation; instead, increase the overall efficiency, and this region should steer towards attracting both foreign and domestic capital and a co-development of export and domestic sales. 3) as for zones with high GDP growth rate and high TFP growth rate, it is necessary to further optimize resource allocations and reasonable utilization, so as to keep a rapid and sustainable development; zones with both low GDP growth rate and low TFP rate should on the other hand strengthen inspections on internal resource allocations and reasonable utilization, find out what the problem is and learn from other more advanced zones, to gradually improve overall management; 4) institutional innovations and innovative mechanisms should be reinforced, theses zones’ management skills to raised achieve all-around improvement in development efficiency; 5) influencing factors of Economic and Technological Development Zones’ development efficiency and unusual samples should be studied in future researches.
