进口贸易自由化与异质性企业创新——来自中国制造企业的证据

摘要基于Heckman两步法,使用2000—2006年海关数据库和工业企业数据库,从不同企业性质、行业性质、地域位置三个维度检验了进口自由化对异质性企业创新行为的影响。结果发现:中间品进口自由化在总体上、在劳动密集型行业和竞争度较大的行业均促进了企业创新,但会抑制垄断行业和资本密集行业的创新活动;最终品进口自由化在总体上、在资本密集行业和劳动密集行业及竞争性行业抑制了企业创新,但促进了垄断性行业、有进口行为的民营企业和中西部地区企业的创新;进口自由化对企业研发投入和新产品产出的影响具有一致性。

But it facilitates innovation in monopoly industries, private importing enterprises and local enterprises in central and western regions.
