基于修正产业辐射强度模型的辽宁省创意产业辐射动态研究

基于断裂点理论，以城市关联度、相对度数中心度和中间中心度指标衡量城市可达性，引入可达性参数对城市间产业辐射强度模型加以改进.以辽宁省14个地级市为研究对象，测算各市2011~2017年创意产业的辐射效应.通过对创意产业空间强度分布结果的比较，分析辽宁省创意产业空间分布和格局演变.研究结果表明:交通便捷性对创意产业发展具有正向作用;辽宁省创意产业联系不紧密;辽宁省的创意产业呈现出两个核心——沈阳市、大连市，两条发展线路——京哈路线和环渤海路线的现象;根据城市发展强度的相似性，应加强同一层级城市的经济联系.

Dynamic Radiation of Creative Industries in Liaoning Province Based on Revised Industrial Radiation Intensity Model

Based on the breaking point theory， urban accessibility was measured by city relevance， relative degree centrality and intermediate center degree index， and the accessibility parameters were introduced to improve the urban radiation intensity model. Taking 14 prefecture-level cities in Liaoning province as the research object， the radiation effects of creative industries in each city from 2011 to 2017 were measured. Through the comparison of the spatial intensity distribution results of creative industries， the spatial distribution and pattern evolution of creative industries in Liaoning province are analyzed. The research results showed that traffic convenience has a positive effect on the development of creative industries. Liaoning’s creative industries are not closely linked and they are represented by two cores—Shenyang city and Dalian city， and two development routes—the Jingha route and the Bohai Sea route. According to the similarity of urban development intensity， economic ties of the same level cities should be strengthened.
