摘要:

目的 分析比较我国东、中、西部医药制造业的出口贸易活动对研发资金投入影响的差异，为提升我国各地区医药制造业研发投入水平和创新能力提供参考。方法 选取1998-2015年我国医药制造业相关数据为样本，根据协整理论，建立误差修正模型并进行格兰杰因果关系检验，以探求二者之间的关系及其影响方向。结果 我国东、中、西部地区医药制造业出口贸易活动对研发资金投入都有滞后性的正向影响，通常在出口贸易活动获益之后1，2，3年对研发资金投入的增长影响较为显著；此外，这种影响按区域排序：西部地区大于东部地区，中部地区最小。建议 相关部门及企业应当重视地区差异，因地制宜、合理地利用出口贸易活动对研发资金投入的正向推动作用，以提升医药制造业研发投入水平。

Abstract:

OBJECTIVE To analyze the differences between the export trade activities of the pharmaceutical manufacturing industry in the eastern, central and western regions of China, and to improve the R&D investment level and innovation ability of the pharmaceutical manufacturing regions in China. METHODS Based on the cointegration theory, the error correction model was established and the Granger causality test was carried out to explore the relationship between the two and the direction of their influence. RESULTS The export trade activities of pharmaceutical manufacturing in the eastern, central and western regions of China had a positive impact on the R&D investment. Generally, after 1, 2, 3 years of R&D, the impact of investment growth was more significant; in addition, this effect was sorted by region:the western region was greater than the eastern region, the central region was minimal. SUGGESTIONS Relevant departments and enterprises should attach importance to regional differences, according to local conditions, rational use of export trade activities on the development of R&D funds to promote the positive role in order to enhance the level of investment in pharmaceutical manufacturing R&D.
