A Shadow‐Price Frontier Measurement of Profit Efficiency in Chinese Agriculture
构建了一个影子价格利润前沿模型，利用农户调查数据检验中国农户的生产效率，发现基于市场价格的利润最大化假设不成立，资源禀赋和教育影响配置效率，减少市场扭曲可提高效率。
Abstract A shadow‐price profit frontier model is developed to examine production efficiency of Chinese farm households. The model incorporates price distortions but retains the advantages of stochastic frontier properties. The shadow prices and shadow profit are derived through a behavioral profit function. Empirical results using household survey data show that the conventional assumption of profit maximization based on market prices is inappropriate. Farmers' resource endowment and education influence their allocative efficiency. Family size, per capita net income, and family members operating as village leaders are positively related to households' production efficiency. Reducing market distortions should increase farm households' production efficiency.
