战略导向、创新能力禀赋与国际化研发强度__基于我国上市公司数据的分析

从影响我国企业研发国际化战略的内生性要素出发,分析了其当前战略中市场导向性和技术导向性与国际化研发强度之间的关系,并从资源角度探讨了企业创新能力禀赋的中介传导作用。在此基础上,以商务部境外投资企业目录中建有海外研发机构的254家上市公司为样本,应用泊松回归对理论分析进行了检验。结果表明:对于存在显著国际化研发战略意图的我国企业来说,其当前战略的市场导向性对国际化研发强度具有显著的抑制作用,而战略的技术导向性对国际化研发具有显著的激发作用;创新能力禀赋对国际化研发强度具有显著正向影响,并且在战略的技术导向性影响国际化研发过程中具有部分中介传导作用。因此,顺应经济高质量发展的时代需要,树立创新为本的战略导向,构建创新发展理念和创新文化传承,强化创新资源和能力的持续积累是我国企业推进国际化研发战略的重要手段。

Research on Urban Mountain Ecological Restoration and Classified Protection Strategies Based on Spatial Identification of Ecological Risk: Taking the West New District of Jinan City as an Example

As an important natural and landscape resource in the city, urban mountain is often invaded to different degrees in the process of rapid growth and disorderly expansion of urban construction land. Yet, as an important part of "Urban renovation and ecological restoration", at present, the practices mainly focuses on single damaged mountain restoration engineering technologies and mountain parks'' constructions. Different from the traditional ecological restoration methods, based on the spatial identification of ecological risks and from the perspective of regional ecological security, this study has constructed a research framework of mountain ecological restoration, which includes "risk diagnosis- spatial identification-pattern construction-classified protection". Based on the ecological risk dynamic assessment and the analysis of dynamic change in NDVI on the mountain of the West New District of Jinan city, this paper identified the important high ecological risk points. The paper and further provides strategies of a mountain ecological protection and restoration space system of "source-corridor-strategic point" according to the integrity of the ecological process an
