从政策观念视角出发,深入探讨长三角区域一体化发展进程,有助于洞察区域内生发展动力和经济增长潜力.应用话语制度主义和间断-均衡框架,结合TF-IDF(词频-逆文档频率)算法与格兰杰检验,揭示长三角一体化发展特征与动因.研究发现:建设主体对5个发展目标的注意力分配不均衡;在创新共建目标方面,地方主体的注意力变动会引起中央主体的注意力变动;长三角一体化发展呈现小间断大均衡特征,体现"自下而上"的地方主导模式.
Exploration of the Characteristics and Dynamics of Integrated Development in the Yangtze River Delta Region:Based on the TF-IDF Algorithm and Granger Causality Test
An in-depth discussion of the Yangtze River Delta regional integration from the perspective of policy idea helps to gain insights into the endogenous development dynamics and economic growth potential of the region.Discourse Institutionalism and Punctuated Equilibrium frameworks were applied,combined with the TF-IDF(term frequency-inverse document frequency)algorithm and Granger test,the characteristics and motives of the Yangtze River Delta integration are revealed.It is found that the construction subjects allocate their attention to the five development goals unevenly;in terms of the innovation co-construction goal,the change in the attention of the local subjects causes the change in the attention of the central subjects.The policy changes of YRD integration are characterized by small interruptions and large equilibrium,reflecting the"bottom-up"local domination mode.
