基于单一横断面数据，先前的研究发现了美国移民“交通同化”的证据：在美国停留的时间与使用公共交通工具呈负相关。本文利用重复的横截面数据重新探讨了这一问题，并考察了交通运输同化随时间的变化趋势。利用1980年、1990年、2000年1%人口普查和2010年(1%)美国社区调查，我研究了移民在美国停留时间与乘坐公共交通工具之间的关系。我首先在四个数据集中分别运行回归：我根据停留时间对公共交通乘客人数进行回归，控制其他个人和地理变量。然后，我比较了四种回归关系的大小。为了研究交通同化率如何随着时间的推移而变化，我汇集了数据集，回归了公共交通乘客停留时间的长短及其与年份假人的互动，以比较不同调查的系数。结果证实了交通同化的结论：随着在美国停留时间的增加，移民使用公共交通工具的次数减少。然而，重复的横截面分析表明，在过去的几十年里，同化率一直在下降。这篇论文发现了交通同化的证据：随着在美国停留时间的增加，移民乘坐公共交通的可能性变得越来越小。然而，随着时间的推移，同化率一直在下降。本文发现，新移民到达后乘坐公共交通的比例、移民的地理分布以及美国移民人口结构的变化对交通同化趋势产生了影响。
Based on single cross-sectional data, prior research finds evidence of “transportation assimilation” among U.S. immigrants: the length of stay in the U.S. is negatively correlated with public transit use. This paper revisits this question by using repeated cross-sectional data, and examines the trend of transportation assimilation over time. Using 1980, 1990, 2000 1% census and 2010 (1%) American Community Survey, I examine the relationship between the length of stay in the U.S. and public transit ridership among immigrants. I first run regressions separately in four data sets: I regress public transit ridership on the length of stay, controlling for other individual and geographic variables. I then compare the magnitudes of the relationship in four regressions. To study how the rate of transportation assimilation changes over time, I pool the data set and regress public transit ridership on the length of stay and its interactions with year dummies to compare the coefficients across surveys. Results confirm the conclusion of transportation assimilation: as the length of stay in the U.S. increases, an immigrant’s public transit use decreases. However, the repeated cross-section analysis suggests the assimilation rate has been decreasing in the past few decades. This paper finds evidence of transportation assimilation: immigrants become less likely to ride public transit as the length of stay in the U.S. increases. The assimilation rate, however, has been decreasing over time. This paper finds that the rate of public transit ridership among new immigrants upon arrival, the geographic distribution of immigrants, and the changing demographics of the U.S. immigrants play roles in affecting the trend of transportation assimilation.
