| 摘 要： | 借助于面板数据模型中的固定效应变截距模型以及出口历史波动率对德州市出口型企业区域内产业集中度和企业规模以及名义汇率与出口之间的关系加以验证,实证结果显示,出口波动与名义汇率变动(主要是美元相对人民币贬值)负相关,出口波动与"区域内产业集中度"正相关,表现为低集中度的产业出口波动更小,在高集中度的行业,出口波动更大。同时,在行业内部,出口规模大的企业出口波动更小,而出口规模小的企业则出口波动更大,调查结果显示这些小企业较大企业议价能力更弱,受到的汇率冲击也更大一些。

| Abstract: | This study uses a panel data fixed effects model with variable coefficients and the historical export fluctuation rates to empirically test the relationship between the intraregional industrial concentration index(IICI),enterprise size,nominal exchange rate and export volatility.The results indicate that nominal exchange rate is negatively correlated with export volatility while IICI is positively associated with export volatility.Within an industry,a firm's export/output ratio reduces export volatility bec... |
