国家战略叠加下区域发展的空间关联及影响因素

Spatial Correlation and Influencing Factors of Regional Development under the Superposition of National Strategies

以“西部大开发”和“黄河流域生态保护和高质量发展”两大国家战略区域为研究对象,基于引力模型,构建经济与生态关联网络,考察网络结构及演变规律,重点考察战略叠加板块发展的空间取向及其影响因素,结果表明:(1)经济网络密度总体呈递增趋势,而生态网络密度则呈递减趋势。各城市经济关联与生态关联强度的差异均逐渐缩小,国家生态保护与高质量发展战略得到了较好的实施。(2)战略叠加板块总体上与黄河流域下游关联更为密切,但与长江流域上游城市的关系提升更快。(3)地理因素仍是影响城市间关系的首要因素,科技、人口因素对经济和生态网络均有影响,而外资和环境规制因素仅对经济关联表现出显著影响。

Taking the two National strategic sectors of“Development of Western Region”and“Ecological Conservation and High-Quality Development of the Yellow River Basin”as the research objects,this study constructed the economic and ecological network based on the gravity model,investigated the network structure and evolution law,and focused on the spatial orientation of the development of the strategic overlay area and its influencing factors. The conclusions are as follows. First,the density of economic network is increasing,while the density of ecological network decreases. The differences in the intensity of economic and ecological linkages among cities are gradually narrowing,and the national ecological protection and high-quality development strategy has been well implemented. Second,the strategic overlay area is more closely related to the lower reaches of the Yellow River Basin,but its relationship with the cities in the upper reaches of the Yangtze River Basin is faster. Third,geographical factors are still the primary factors affecting the inter city relationship. Science and technology,population factors have an impact on the economy and ecological network,while foreign investment and environmental regulation factors only have a significant impact on the economic relationship.
