講座標題:Railways, Telegraph and Technology Adoption: The Introduction of American Cotton in Early 20th Century China

要:We present a new source of gains from infrastructure, technology adoption. Through the lens of a heterogeneous agent model with trade and information frictions, we explore how infrastructure increases welfare through the endogenous adoption of a new agricultural technology-a high-quality variety of American cotton-in early 20 th century China. Using historical data, our empirical tests reveal that counties that had access to the railway and telegraph networks were more likely to cultivate American cotton, since these infrastructures decreased the take-up thresholds. As predicted by the model, counties that were less suitable for cultivating cotton and households with smaller farms experienced larger increases in the adoption of American cotton if they were connected to these infrastructures. The contribution of the additional technology adoption margin to the overall welfare gains from infrastructure is quantitatively large.

講座標題:鐵路、電報與技術引進:20世紀初美國棉在中國的傳播

要:本文提出了基礎設施收益的新來源——技術引進。通過建立包含貿易和信息摩擦的異質性代理人模型,本文探討了20世紀初,中國的基礎設施如何通過促進新的農業技術——高質量的美國棉的引入提高福利水平。基于歷史數據的實證分析表明,接入鐵路和電報網絡的縣更有可能種植美國棉,因為這些基礎設施降低了技術引進的門檻。正如模型預測的,在接入這些基礎設施后,棉花種植條件較差的縣和擁有較小農場的家庭更傾向于引進美國棉。技術引進對基礎設施帶來的整體福利增益具有顯著的貢獻。
