县域经济增长中结构红利的测度及决定 ——基于中国1 820个县面板数据的实证分析

产业结构升级是经济增长的源泉之一。本文基于中国1 820个县的面板数据，采用Translog生产函数估计要素弹性，进而测度县域经济增长中的结构红利，同时构建空间误差计量模型对结构红利的影响因素进行检验。研究结果表明2002-2010年间，结构红利占县域GDP总值的444%，对县域GDP增长的贡献达到了2435%。劳均资本、劳均土地等变量对结构红利有显著影响，本文还发现，在东部、中部、西部三个地区，财政支出占GDP的比重对结构红利都有显著的负向影响。

THE MEASURE OF STRUCTURAL BONUS AND INFLUENCE FACTORS IN COUNTY ECONOMY ——Evidence from 1 820 Counties in China

The upgrade of industrial structure is the source of economic growthBased on the panel data of 1 820 counties in China，this paper estimates elasticity of production factors with the Translog production function and makes the further measure of structural bonusThe results show that contribution of structural bonus to the GDP in county economy reaches 444% and to the growth rate of GDP is 2435%The spatial econometric model examines that the per capita capital and per capita cultivated land area have significant effect on structural bonus，and in the three areas，the structure of fiscal expenditure proportion in GDP has significant negative impact on structural bonus
