基于 2003-2019 年 213 个地级市面板数据,将智慧城市试点作为一项衡量数字经济发展的准自然实验,构建多时点双重差分模型,实证检验数字经济对农业生产性服务业的影响效应和作用机制.研究表明:(1)数字经济显著促进了农业生产性服务业发展,且这一结论在经过平行趋势、安慰剂等多种方法检验后依然稳健.(2)"需求-供给"两端分析表明,促进非农就业和资本、技术和信息等要素供给是数字经济推动农业生产性服务业发展的重要路径.(3)数字经济对农业生产性服务业的促进作用,在东部地区以及传统基础设施和规模化种植较为完善的城市更明显.(4)城镇化在数字经济与农业生产性服务业之间具有显著"单一"门槛效应,只有在人口、产业和土地城镇化达到一定水平时,数字经济才能发挥出对农业生产性服务业发展的促进作用.
Impact of the Digital Economy on Agricultural Productive Services:Perspectives from Non-agricultural Employment and Factor Supply
This research,utilizing panel data from 213 prefecture-level cities between 2003 and 2019,employs smart city pilots as a quasi-natural experiment in evaluating digital economy growth.A multi-timepoint difference-in-differences model was developed to empirically assess how the digital economy impacts the agricultural productive service sector.The study confirms that the digital economy significantly fosters this sector's growth,with robustness evident after various validation methods like parallel trend analysis and placebo tests.A dual perspective analysis,focusing on both demand and supply,reveals key pathways for this impact:fostering non-agricultural employment and enhancing the availability of capital,technology,and information.This positive influence is especially noticeable in China's eastern regions and in cities with advanced traditional infrastructure and extensive cultivation practices.Additionally,the study highlights a critical threshold effect of urbanization in the digital economy-agricultural productive service industry nexus.The digital economy's beneficial role in this sector's development becomes pronounced only when urbanization—in terms of population,industry,and land—reaches a certain level.
