The hypothesized relationship between economic expansion and accident injuries is tested using archival economic and accident data from the Los Angeles-Long Beach, California metropolitan area. The association is measured using cross-correlation techniques after variation shared with a comparison metropolitan area (Anaheim-Santa Ana-Garden Grove) is removed. Two tests of association are conducted. The first uses the raw accident rate of the comparison metropolitan area as a control variable while the second adjusts the control variable to reflect shared industrial sectors. Findings suggest that the incidence of disabling accidents increases in the month before and during the month that the manufacturing work force expands. The impact appears strongest during the month that new workers are added.
利用来自加利福尼亚州洛杉矶 - 长滩大都市区的档案经济和事故数据，对经济扩张与事故伤害之间的假设关系进行了检验。在去除与对比大都市区（阿纳海姆 - 圣安娜 - 加登格罗夫）共享的变化因素后，使用互相关技术来衡量这种关联。进行了两项关联测试。第一项测试将对比大都市区的原始事故率用作控制变量，而第二项测试则对控制变量进行调整，以反映共享的工业部门。研究结果表明，在制造业劳动力扩张前一个月和扩张当月，致残事故的发生率会增加。在新增工人的那个月，这种影响似乎最为强烈。
