外国投入品市场中的市场势力：来自中国制造企业的证据
Market Power in Foreign Input Markets: Evidence From Chinese Manufacturing Firms
摘要
Large manufacturers may obtain better terms from foreign suppliers when they account for an important share of demand. We study this buyer power using matched customs and production data for Chinese manufacturing firms from 2000 to 2007. Measuring buyer power for each imported product and source country reveals substantial differences across firms that aggregate input measures conceal. Pure processing‐trade firms have higher average buyer power, whereas pure ordinary‐trade firms experience larger increases over time. Within firms, buyer power is higher when processing trade accounts for a larger share of imports and when input tariffs are lower. Together, these patterns connect firms' purchasing leverage to their trade regime and exposure to input tariffs.
中文摘要
大型制造商在需求中占据重要份额时，可能从外国供应商处获得更有利的条件。我们利用2000年至2007年中国制造业企业的匹配海关与生产数据，研究这种买方力量。针对每种进口产品和来源国衡量买方力量，揭示了企业间存在显著差异，而这些差异被加总的投入品指标所掩盖。纯加工贸易企业的平均买方力量较高，而纯一般贸易企业的买方力量随时间增长幅度更大。在企业内部，当加工贸易占进口比重更大且投入品关税更低时，买方力量更强。综合来看，这些模式将企业的采购议价能力与其贸易方式和投入品关税暴露联系起来。
