Abstract

The chemical fertilizer industry has made great contributions to China's food security. Existing studies mainly focus on evaluating fertilizer use efficiency at the farm level whereas little is known about the technical efficiency of Chinese firms producing fertilizer. Based on the Chinese Industrial Enterprise Database (CIED) and the Generalized True Random Effects model (GTRE), this paper estimates and decomposes the technical efficiency of Chinese fertilizer-producing firms. Results show technical efficiency increased from 0.883 in 1998 to 0.930 in 2007, with an average of 0.898. The growth rate of persistent efficiency is lower than that of transient efficiency, implying structural problems exist in the Chinese fertilizer industry. Moreover, ownership type and firms' entry and exit are exogenous determinants of technical inefficiency. State-owned firms perform much worse on technical efficiency. The entry of efficient firms and exit of inefficient firms, especially the exit of inefficient state-owned firms, have improved the technical efficiency significantly.

中国化肥企业的持续和短暂效率:所有权重要吗?

化肥工业为中国的粮食安全作出了巨大贡献。现有的研究主要集中在农场层面的肥料利用效率评价，而对我国肥料生产企业的技术效率了解甚少。本文基于中国工业企业数据库(CIED)和广义真随机效应模型(GTRE)，对我国化肥生产企业的技术效率进行了估计和分解。结果表明:技术效率由1998年的0.883提高到2007年的0.930，平均为0.898;持续效率增速低于短暂效率增速，说明我国化肥行业存在结构性问题。此外，所有制类型和企业进入和退出是技术无效率的外生决定因素。国有企业在技术效率上的表现要差得多。高效企业的进入和低效企业的退出，特别是国有低效企业的退出，显著提高了技术效率。
