The role of hindrance stressors in the job demand–control–support model of occupational stress: A proposed theory revision

Previous research on the job demand–control–support (JDCS) model of occupational stress has generally been inconsistent at best regarding a key issue: the interaction of demands, control, and support in predicting employee health and well‐being. However, the model continues to be tested in a variety of studies and academic journals owing to its intuitive appeal. By incorporating conservation of resources theory with knowledge from the challenge–hindrance stressor framework, we proposed that hindrance stressors, not the challenge stressors commonly assessed when testing JDCS theory, will provide validation for the model. A two‐wave panel study of 228 employees in a variety of occupations provided support for three‐way interactions between hindrance demands, control, and support predicting job‐related anxiety and physical symptoms. Three‐way interactions using a challenge demand (forms of workload) were not significant, consistent with our propositions. In summary, this study supports the buffering effect of control and support on the relationship between job demands and strain only when job demands reflect hindrance stressors, thereby proposing to alter the JDCS model by specifying that it applies primarily to hindrance stressors in a job hindrance–control–support model.

过江通道建设对相对落后地区发展的影响——以江苏省南通市为例

苏通大桥及沪崇苏通道的建设将引致区域交通格局的演化，从而对相关地区经济社会发展产生深远影响。对于相对落后的南通市而言，快速过江通道建设既是促进发展的良好机遇，同时也将带来新的挑战和威胁：（1）交通可达性改善明显，南向联系趋于便捷，运输成本相应减小，要素集聚呈现加速态势，但优质要素面临流失威胁；（2）产业规模迅速扩张，但以低层次产业为主，进一步加大了产业层次提升的压力，同时建设用地的盲目扩张和散乱布局，使得空间开发无序风险加剧；（3）进入上海都市圈的紧密圈层，有望成为长江三角洲北翼重要的次中心城市，但面临的竞争压力也不断增大。为促进南通市的可持续发展，政府部门应在推进都市区建设、促进要素集聚、空间资源的合理和统筹利用等方面制定科学有效的区域政策。
