摘要：

本文基于1997—2010年267个地级及以上城市市辖区面板数据，运用标准化供给面系统方法测算了市级层面的技术进步方向，并借助“撤县设区”这一自然实验，利用工具变量法实证检验了要素结构变动对技术进步方向的影响，研究发现：（1)“撤县设区”使得资本—劳动比上升，进而导致技术进步方向偏向于资本，符合偏向型技术进步的“弱诱导偏向型假说”；（2)“撤县设区”对资本偏向型技术进步的影响是有条件的，主要限于资本—劳动替代弹性大于1即资本—劳动呈替代关系的地区；（3)相比于中西部地区，东部地区资本要素更为丰富，因而“撤县设区”显著提高了东部地区的资本—劳动比，使其技术进步方向偏向资本。

Abstract:

Based on the panel data of 267 prefecturelevel cities from 1997 to 2010, this paper uses the normalized supplyside system approach to measure the technical progress direction at the municipal levelBy the natural experiment of “CityCounty Merger”, we investigate the effect of factors structure change on the direction of technical change with the instrument methodThe study shows as follows: “CityCounty Merger” makes the capitallabor ratio rise and induces to the capitalbiased technical change, which is in line with the “weak induced bias hypothesis”.The effect of the “CityCounty Merger” on the technical progress of capital bias is conditionally limited to the area where capitallabor substitution elasticity is greater than 1 that means that capitallabor is substituted mutuallyCompared to the central and western regions, “CityCounty Merger” significantly increases the capitallabor ratio in the eastern region due to more abundant capital, which makes the direction of technical change biased towards capital

Key words: CityCounty Merger , factors structure , elasticity of substitution , directed technical change
