本文基于多种估算模型和稳健标准误的统计推断，按照资金来源测算了西部地区固定资产投资与经济增长之间的线性关系系数和弹性关系系数，使用单边随机边界模型测算了固定资产投资各类资金的投资效率和各类资金的总体投资效率。实证结果表明，国家预算资金和其他资金的线性和弹性系数不显著，国内贷款、利用外资和自筹资金的线性关系系数测算的平均值分别为2.308、23.794和1.505，弹性关系系数的平均值分别为0.15、0.054和0.416；西部地区固定资产投资效率总体高于70%。

Based on a variety of estimation model and statistical inference with robust standard errors, the paper estimates the lin-ear and elastic relationship coefficient between fixed asset investment and economic growth in the western region according to funding sources, and uses unilateral stochastic frontier model to estimate the single efficiency of single fixed assets investment and overall effi-ciency of all fixed assets investment. The empirical results show that the linear and elastic coefficient of the state budgetary appropria-tion and other funding are not significant, while the measure of the average coefficient of linear relationships of domestic loans, foreign investment and self-raised funding are 2.308, 23.794 and 1.505 respectively, and the average coefficient of elasticity relationships are 0.15, 0.054 and 0.416. The overall fixed asset investment efficiency in the western region is higher than 70%.
