摘要

本文采用污染技术的多方程模型来评价过量氮的边际减排成本。使用凸非参数分位数回归估计MAC。以2017年法国小麦生产为例，在地块水平上进行了实证应用。结果显示，多余氮的影子价格中值约为每公斤21欧元。如果目前欧盟的硝酸盐指令(每公顷有机氮限制为170公斤)扩展到矿物氮，这将使总过量氮减少9.5%，但这将伴随着小麦收入减少3.1%。

Cost of abating excess nitrogen on wheat plots in France: An assessment with multi-technology modelling

We use a multi-equation model of polluting technologies to evaluate excess nitrogen's marginal abatement cost (MAC). The MAC is estimated using the convex non-parametric quantile regression. The empirical application is conducted at the plot level for wheat production in France in 2017. Results show a median shadow price for excess nitrogen of about €21 per kilogram. If the current European Union's Nitrates Directive (which sets a 170-kg constraint on organic nitrogen per hectare) were extended to mineral nitrogen, this would allow a reduction of total excess nitrogen by 9.5%, but this would be accompanied by a 3.1% decrease in wheat revenue.

期刊介绍： Published on behalf of the Agricultural Economics Society, the Journal of Agricultural Economics is a leading international professional journal, providing a forum for research into agricultural economics and related disciplines such as statistics, marketing, business management, politics, history and sociology, and their application to issues in the agricultural, food, and related industries; rural communities, and the environment. Each issue of the JAE contains articles, notes and book reviews as well as information relating to the Agricultural Economics Society. Published 3 times a year, it is received by members and institutional subscribers in 69 countries. With contributions from leading international scholars, the JAE is a leading citation for agricultural economics and policy. Published articles either deal with new developments in research and methods of analysis, or apply existing methods and techniques to new problems and situations which are of general interest to the Journal’s international readership.
