Coupling coordinated development among digital economy,regional innovation,and talent employment:A case study in the Hangzhou Metropolitan Circle,China

Coordinative development across various systems,particularly the economic,social,cultural,and human resources subsystems,is a key aspect of urban sustainability and has a direct impact on the quality of urbanization.The Hangzhou Metropolitan Circle,comprising Hangzhou City,Huzhou City,Jiaxing City,and Shaoxing City,was the first metropolitan circle approved by the National Development and Reform Commission(NDRC)as a demonstration of economic transformation in China.To evaluate the coupling coordination degree of the four cities and analyze the coordinative development in three systems(including digital economy,regional innovation,and talent employment),we collected panel data during 2015–2022 from these four cities.The development level of the three systems was evaluated by the standard deviation method and comprehensive development index.The results are as follows:(1)the level of coupling coordinated development of the three systems in the Hangzhou Metropolitan Circle was relatively low;(2)the coupling coordination degree of the four cities in the Hangzhou Metropolitan Circle showed significant regional differences,among which Hangzhou City was in the leading position,and Huzhou,Jiaxing,and Shaoxing cities made steady but slow progress in the coupling development of the three systems;and(3)the development of digital economy and talent employment needs to be strengthened.This study contributes to the coordinative development of Hangzhou Metropolitan Circle by innovatively focusing on the coupling coordination relationship among digital economy,regional innovation,and talent employment,which also meets the industrial layout of Hangzhou Metropolitan Circle.In this way,the optimal allocation and sustainable development of digital economy,regional innovation,and talent employment in the Hangzhou Metropolitan Circle can be achieved.

Analysis of Chinese Manufacturing Export Duration

This paper studies the duration of Chinese manufacturing exports and its determinants, using disaggregated 6-digit level Harmonized System product trade data from 1995 to 2007. Cox proportional hazard, Weibull and exponential models are used to examine the effects of various factors on export duration. It is revealed that export duration tends to be rather short-lived. It is also found that GDP and GDP per capita of the export destination have positive effects on export duration, while trade relationships with distant and landlocked countries are generally of shorter duration. In addition, export duration is longer for differentiated and parts and components products, as well as products with large initial trade values. WTO membership is also important for longer export duration. Our empirical analysis suggests that developed markets, such as the USA and the EU, are important to China, and should still be the major sources for Chinese export growth in the long run. Moreover, technical innovation of firms and free trade agreement negotiations will be helpful for sustainable export growth.
