农业产业集聚与县域经济增长——来自河南现代农业产业园设立准自然实验的证据

Agricultural Industrial Agglomeration and County Economic Growth:Evidence from the Establishment of Henan Modern Agricultural Industrial Park

以河南现代农业产业园的设立为准自然实验,利用2013—2021年河南省县级面板数据,构建多时点双差分模型考察农业产业集聚对县域经济增长的影响。研究表明:(1)现代农业产业园的设立显著推动了县域经济增长,这一结论在多项稳健性检验后仍然成立;(2)要素集聚、农业技术进步与产业融合是农业产业集聚驱动县域经济增长的主要机制,其中一二三产业协同形成的农业技术进步与产业融合,是其有别于传统制造业集聚的特有机制;(3)农业产业发展基础、经济结构以及财政支持强度均会对农业产业集聚的经济增长效应产生异质性影响,即农业产业基础弱、工业基础扎实和强财政支持产业园的县域,其农业产业集聚的经济增长效应更显著。

This article treats the establishment of the Henan Modern Agricultural Industrial Park as a quasi-natural experiment.Utilizing panel data from county-level administrative units in Henan Province spanning from 2013 to 2021,we construct a multi-timepoint differences-in-differences model to examine the impact of agricultural industrial agglomeration on county economic growth.The study reveals that:(1)The establishment of the modern agricultural industrial park significantly propels county economic growth,a conclusion that holds true even after conducting various robustness checks.(2)Factor agglomeration,agricultural technological progress,and industry integration constitute the primary mechanisms through which agricultural industrial agglomeration drives county economic growth.Notably,the unique mechanism of agricultural technological progress and industry integration formed through the synergistic collaboration of the primary,secondary,and tertiary sectors distinguish it from the agglomeration observed in traditional manufacturing industries.(3)The economic growth effects of agricultural industrial agglomeration are subject to heterogeneous influences from natural endowments,economic structure,and the level of agricultural support.Specifically,counties with favorable agricultural foundations,robust industrial bases,and greater support for industrial parks exhibit more pronounced economic growth effects resulting from agricultural industrial agglomeration.
