【摘要】 开发区作为产业集聚的核心载体，是地区经济增长的重要引擎。但其在转型升级过程中往往面临产业同质化和盲目竞争等挑战，而积极响应开发区构建共生互补产业体系的政策目标、推动开发区良性互动发展则是解决这一问题的关键。论文以长三角地区97个国家级开发区为研究对象，基于技术互动理论，综合技术互补与竞争指数、社会网络分析和二次指派程序(quadratic assignment procedure,QAP)等方法，分析了1985—2021年开发区技术互动的演变特征与影响因素。研究发现：(1)长三角地区国家级开发区的技术互动经历了低位波动期、消长分异期和同步增长期三个阶段，并呈现出由竞争和互补并行到以技术互补为主的动态演化过程。(2)国家级经济技术开发区和国家级高新技术开发区的技术互动趋势大致相同，但后者技术互动的强度更高。(3)开发区的技术互动网络逐步成熟，技术互补网络呈现“多核心—多层次—广覆盖”的“菱形”结构，社团之间联系日益紧密，而技术竞争网络呈现出“多点开花”的局面。(4)开发区技术互动初期受所在城市的行政区隔和城市行政等级的影响较大；中期跨区域合作逐渐兴起，城市行政等级差异的影响增加；后期则更多由开发区本身的地理邻近性和主导产业结构相似性驱动，反映了开发区技术互动由行政导向下依赖城市联系转向市场导向下自发驱动的变化。研究拓展了技术互动理论的知识边界，深化了开发区协同发展的研究进展，并提供了来自技术要素这一底层架构的知识贡献。更多还原

【Abstract】 Development zones serve as core carriers of industrial agglomeration and are important engines of regional economic growth. However, during their transformation and upgrading, they often encounter challenges such as industrial homogeneity and blind competition. To address these issues, it is essential to actively respond to policy initiatives that aim to build a symbiotic and complementary industrial system in development zones and foster positive interactions among them. This study focused on 97 national-level development zones in the Yangtze River Delta region and, based on the theory of technology interaction, employed technology complementarity and competition index, social network analysis, and quadratic assignment procedure(QAP) methods to analyze the change and influencing factors of technology interaction from 1985 to 2021. The findings indicate that: 1) The technology interaction in the national-level development zones in the Yangtze River Delta region has gone through three stages—fluctuation at a low level, differentiated growth and decline, and synchronous growth—and presented a dynamic change process from competition and complementarity to technology complementarity. 2) The trends in technology interaction between national-level economic development zones and high-tech zones were generally similar, but the latter exhibited a higher intensity of interaction. 3) As the technology interaction network matures, the technology complementarity network has evolved into a "multi-core, multi-level, and widecoverage" diamond-shaped structure, with increasingly close connections among the communities, while the technology competition network presents a decentralized "multi-point blossoming" pattern. 4) In the early stage, technology interaction was significantly influenced by administrative boundaries and hierarchical differences between cities. In the middle of the development stage, cross-regional cooperation emerged, and the impact of urban hierarchy increased. In the later stage, geographical proximity and industrial structure similarity became the primary drivers, reflecting a shift from government-led, city connection-dependent to market-driven, selfinitiated cooperation. This study expands the theoretical boundaries of technology interaction, further deepens the research progress of coordinated development of development zones, and provides a contribution of knowledge based on the fundamental structure of technology elements.更多还原
