長三角一體化綜合測度與協同治理研究

[摘 要：打破“以鄰為壑”，探究協同治理模式成為長三角城市群戰略性選擇。文章從區域協調發展、創新產業共建、基礎設施服務、生態環境共保和高水平協同開放五個方面構建綜合評價指標體系，運用社會網絡分析方法綜合測度長三角一體化水平，分析2012—2020年長三角各城市一體化水平差異與動態演進特征，并構建三方演化博弈模型，揭露長三角城市協同治理內在機理。研究發現：長三角東部城市一體化水平顯著高于西部城市；長三角一體化水平較高城市主要集中在早期加入長三角城市群的城市；長三角一體化水平總體差異主要源于省域間差異；長三角城市協同治理模式趨向于常態化參與一體化發展，政府獎勵并不是越高越好。

關鍵詞：長三角一體化；核密度估計；綜合測度；協同治理

Abstract：It has become a strategic choice for the Yangtze River Delta city cluster to break the “beggar-thy-neighbor” and explore the collaborative governance model. This paper constructs a comprehensive evaluation index system from five aspects：coordinated regional development，innovation industry co-build，infrastructure service，ecological environment co-protection，and high level of synergy and openness，measures the integration level of the Yangtze River Delta using social network analysis，analyzes the differences and dynamic evolution characteristics of the integration level of Yangtze River Delta cities between 2012 and 2020，and constructs a three-party evolutionary game model to reveal the inner mechanism of Yangtze River Delta city. It is found that the integration level of the eastern cities in the Yangtze River Delta is significantly higher than that of the western cities；the cities with higher integration level in the Yangtze River Delta are mainly concentrated in the cities that joined the Yangtze River Delta city cluster in the early stage；the main source of the overall difference in the integration level in the Yangtze River Delta is the inter-provincial differences；the collaborative governance model of the Yangtze River Delta cities tends to participate in the integration development in a regular manner，and the higher government incentives are not better.

Key words：Yangtze River Delta integration；kernel density estimation；integrated measurement；collaborative governance

一、引 言

黨的二十大著重強調，高質量發展是全面建設社會主義現代化國家的首要任務，要“以城市群、都市圈為依托構建大中小城市協調發展格局”。長三角城市群作為國家戰略發展規劃示范區，在實施區域協調發展戰略中擔當重要角色，《長江三角洲區域一體化發展規劃綱要》（以下簡稱《規劃綱要》）要求，到2035年，長三角一體化發展機制更加完善，整體達到全國領先水平，成為最具影響力和帶動力的強勁活躍增長極［1］。然而，長三角城市群相較于世界級城市群依然存在一定差距，城鄉發展不平衡、區域發展差異是長三角城市高質量發展的突出短板。……
