摘　　要：为探究高速公路网建设对中国农机跨区作业服务市场形成脉络的影响,从供给端和需求端2个角度探讨了高速公路网建设推动农机跨区服务市场发育的作用机理,并利用2000—2019年17个稻麦主产省份面板数据展开实证检验。结果表明:1)在理论上,高速公路网建设不仅通过交通时间收敛效应这一中间机制提高服务主体跨区服务意愿和能力,且提高服务主体进入某一区域的便捷性和及时性进而刺激当地农户形成农机跨区服务需求。2)2000—2013年的回归结果表明,高速公路网建设对农机跨区服务供给具有显著的促进作用,高速公路网密度增加对跨区机收面积占比增长的贡献率为47.78%,而高速公路密度差异对跨区机收服务供给能力区域差异的贡献率为13.8%。3)2014—2019年的回归结果显示,高速公路网建设对农机跨区服务需求具有显著的推动作用,高速公路密度每增加1个单位,跨区机收稻麦服务需求强度相应增加8个百分点,且高速公路密度区域差异对跨区机收稻麦服务需求强度区域差异的贡献率为12.1%。To explore the impact of expressway network construction on the formation of China’s cross regional agricultural machinery operation service market,the study discusses the mechanism of the highway network construction to promote the development of the agricultural machinery cross-regional service market from the supply side and the demand side,and uses the panel data of the 17major rice and wheat producing provinces from 2000to2019to conduct empirical tests.The results show that:1)In theory,the construction of expressway network improves the cross regional service willingness and ability of service subjects through the intermediate mechanism of traffic time convergence effect.The convenience and timeliness of service subjects entering a certain area are conducive to stimulate local farmers to form cross-regional agricultural machinery service demand.2)The regression results from2000to 2013show that the construction of expressway network plays a significant role in promoting cross-regional agricultural machinery service supply.The contribution rate of the increase of expressway network density to the growth of cross-regional machine harvesting area is 47.78%,while the contribution rate of expressway density difference to regional differences in the supply capability of cross-regional agricultural machinery service is 13.8%.3)The regression results from 2014to 2019also show that the construction of expressway network plays a significant role in promoting cross-regional agricultural machinery service demand.For every 1unit increase in expressway density,the cross-regional agricultural machinery service demand intensity increases by 8percentage points,and the explanatory power of regional difference in expressway density to spatial differentiation of cross-regional agricultural machinery service demand is 12.1%.
