THE LOCATIONAL DYNAMICS OF MANUFACTURING IN CHINA'S COUNTIES: INFLUENCE OF EXPRESSWAY INVESTMENT
研究了2001-2005年间高速公路投资对中国县域制造业分布的影响，发现高速公路可达性使内陆县域制造业就业增长约41%，但对沿海高密度地区效果有限，且靠近大城市的县域受益更多。
ABSTRACT This study investigates the impact of expressway investment in China's counties. By identifying expressway accessibility through toll station locations, we estimate the manufacturing distribution along expressways for 2001–2005. We find that expressway accessibility promotes manufacturing employment for inland counties by around 41 percent; however, for coastal counties that already have high road density and dense manufacturing layouts, the returns from new expressways are small. Furthermore, counties close to large cities benefit more from expressway accessibility than do counties that are far from them. The gap first increases in the period of expressway construction and then decreases as expressway effects are smoothed.
