An empirical analysis of household choices on housing and travel mode in Boston, Annals of Regional Science, 2010, 45(2): 423-438 (with T.R. Lakshmanan, Chun-Yu Ho and William P. Anderson)

波士顿家庭住房和出行方式选择的实证分析 《区域科学年鉴》，2010年，45(2)期，423-438页（与 T.R. Lakshmanan、Chun-Yu Ho 、William P. Anderson合著）

Abstract：
We study household choices on the housing type and travel mode in Boston in the year 1991.We first develop a theoretical model for an integrated analysis of housing and travel mode choices, which implies that people with higher income level tend to live farther away from the Central Business District, enjoy more spacious housing and travel with a speedier mode. Logit estimation methods are employed to analyze the 1991 Boston Household Survey data. Our empirical results provide indirect confirmation of the theoretical model.

摘要：

本文研究了 1991 年波士顿家庭对住房类型和出行方式的选择。笔者首先建立了一个理论模型来综合分析住房和出行方式的选择，模型显示收入水平较高的人群通常住在离中央商务区更远的地方，享受更宽敞的住房和更快的出行方式。本文使用了Logit 评估方法分析 1991 年波士顿家庭的调查数据，其实证结果亦间接证实了理论模型。

Rising regional income inequality in China: Policy regimes and structural changes, Papers in Regional Science, 2008,87(2): 245-259 (with Chun-Yu Ho)

中国区域收入不平等上升：政策体制与结构变化 《区域科学论文集》，2008年，87(2)期，245-259页（与Chun-Yu Ho合著）

Abstract：
Regional inequality is severe in China since regional development is uneven due to various initial conditions and government policies. We employ unit root tests allowing for structural breaks to alternative inequality measures from 1952 to 2000. Empirical results indicate that (1) the regional inequality is trend stationary with structural breaks rather than following a random walk. Thus, ignoring structural changes might leads to incorrect inference and misleading policy implications; (2) the break points are associated with episodic events in Chinese economic history such as the Cultural Revolution and market reforms. This implies that the policies had a long-lasting and fundamental effect on the inequality.

摘要：

由于各种初始条件和政府政策导致区域发展不平衡，中国出现严重的区域收入差距现象。笔者采用允许结构性断点的单位根检验方法分析了1952至2000年间的关于收入不平等的不同衡量指标。实证结果表明：第一，区域不平等时间序列呈现趋势稳定但具有结构性断点的特性，并非随机游走的。因此，忽视结构性断点可能会导致错误的推断和误导性的政策；第二，断点与中国经济史上的发生事件有关。这意味着这些政策对不平等现象产生了长期的根本性影响。

Interregional productivity variations in Chinese manufacturing and mining industry, Applied Economics Letters, 2008, 15(14):1073-1077  

中国制造业和采矿业的区域间生产率差异，《应用经济学快报》，2008年，15(14)期，1073-1077页

Abstract：
A shift-share model is employed to analyze the interregional productivity variations in Chinese manufacturing and mining industry. Our empirical results show that sector productivity difference is huge; surprisingly, the most productive coastal regions are found to be specialized in low productive sectors; the inland provinces suffer a uniform productivity lag, which suggests policies geared to increase regional productivity, such as infrastructures and human capital, are crucial to close the productivity gap between the inland and the coast.

摘要：

本文采用了偏离份额分析模型（shift-share model）分析中国制造业和采矿业的区域间生产率的差异。实证结果表明，部门生产率差异巨大；出乎意料的是，生产力最高的沿海地区反而专长于低生产力部门；内陆省份的生产力普遍滞后。这表明提高区域生产力的政策对于缩小内陆和沿海地区的生产力差距至关重要，如基础设施和人力资本建设。
