长三角区域一体化高质量发展：问题与出路

长三角一体化高质量发展对于中国经济行稳致远有着不言而喻的重要意义。为了科学全面认识新时代长三角一体化高质量发展中存在的问题,厘清未来的发展出路,邀请来自不同领域的相关专家就长三角一体化高质量发展中的区域协调、产业协同、交通组织、城镇体系演变、跨区合作、要素配置、流域统筹、一体化路径、绿色低碳发展等研究前沿进行访谈。访谈结果表明：长三角作为我国经济发展最活跃、开放程度最高、创新能力最强的区域,其发展中仍然存在内部发展不平衡、区间交通割裂、行政壁垒尚存、流域生态协作不健全、产业协同发展不足、绿色经济体系较弱等突出问题。长三角在中国乃至世界发展格局中的战略地位,需要综合各学科各专业的理论知识,从不同视角持续关注长三角一体化高质量发展的重大科学命题。紧扣“一体化”和“高质量”,长三角一体化首先要创新机制缩小区域内部发展差异,强化综合交通一体化的基础支撑,更要突破行政边界的制约;其次要创新机制体制来保障生产要素的有效流动与配置,通过价值链、产业链、创新链的融合发展来夯实一体化;再次要促进土地要素向长三角集中使用,提高长三角地区土地承载能力,为长三角区域一体化高质量发展提供充足的土地要素保证;然后要优化人口就业空间结构,加强城际间环境污染联防联治,强化大江大河等重大流域的省际统筹与合作,共同提升长三角的生态系统服务功能,推动绿色一体化发展;最后更要贯彻五大新发展理念,通过科研突破与市场机制来实现低碳发展,在创新驱动引领下打造流空间世界级枢纽,以实现长三角区域一体化高质量发展的新局面。以上观点为长三角区域一体化高质量发展提供科学可行的理论和决策支持。

High-quality integrated development in the Yangtze River Delta region: Problems and solutions

The integrated high-quality development of the Yangtze River Delta (YRD) is of great importance for the long-term development and stability of China's economy. In order to scientifically and comprehensively understand the problems existing in the development of the YRD in the New Era and clarify the future development path, experts from different fields are invited to discuss the regional coordination, industrial coordination, and transportation organization. Interviews were conducted on research frontiers such as urban system evolution, cross-regional cooperation, factor allocation, river basin planning, integration paths, and green and low-carbon development. The interview results show that the YRD is the region with the most active economic development, the highest degree of openness and the strongest innovation ability in China. But it is still characterized by prominent problems, such as unbalanced internal development, fragmented inter-regional traffic, remaining administrative barriers, unsound river basin ecological cooperation, insufficient coordinated industrial development and weak green economic system. The strategic position of the study area in the development of China and the world requires the integration of theoretical knowledge of various disciplines and subjects, and continuous attention to the major scientific proposition of the integrated high-quality development of the delta region from different perspectives. Closely related to "integration" and "high quality", the integration of the YRD should first innovate the mechanism to narrow the development differences within the region, strengthen the basic support for comprehensive transportation integration, and break through the constraints of administrative boundaries. Secondly, to innovate the mechanism and system to ensure the effective flow and allocation of production factors, through the integration and development of the value chain, industrial chain, and innovation chain to consolidate the integration; again, to promote the centralized use of land elements in the YRD, improve the land carrying capacity of the YRD, and integrate the whole delta region. High-quality development provides sufficient land element guarantee. Thus, it is necessary to optimize the spatial structure of population and employment, strengthen inter-city environmental pollution prevention and control, advance inter-provincial coordination and cooperation in major river basins, improve the ecosystem services function and promote green integrated development in the YRD. Finally, we should develop new concepts, achieve low-carbon development through scientific research breakthroughs and market mechanisms, and build a world-class hub of flow space under the guidance of the national innovation-driven strategy, so as to create a new situation in the high-quality integration of the YRD region. The above viewpoints provide scientific and feasible theoretical and decision support for the integrated high-quality development of the YRD.
