Multi-dimensional boundary effects and regional economic integration: Evidence from the Yangtze River Economic Belt

While the challenges posed by multi-dimensional boundary effects to global economic integration are studied widely, regional economic integration within a sovereign country requires additional analysis. The Yangtze River Economic Belt (YREB), a super-scale interprovincial area including three nested urban alliances, is a meaningful vision of regional economic integration in China. After building the producer services-based urban corporate network, this study investigates the influence of multi-dimensional boundary effects on regional economic integration by social network analysis and the exponential random graph model. The findings show that the fragmented reality of YREB’s economy is significantly different from the vision of the Chinese central government. More specifically, although the natural boundary restraints represented by distance have disappeared, multi-dimensional barriers to regional economic integration are still posed by administrative, policy, economic, and cultural boundaries. The estimation results pass the robustness test of the grouping sample of producer services. Therefore, we confirm that the multi-dimensional boundary effects, particularly the intangible ones, significantly impact regional economic integration even within a country with a top-down ‘strong’ governance.

Does the Agglomeration of Producer Services and the Market Entry of Enterprises Promote Carbon Reduction? An Empirical Analysis of the Yangtze River Economic Belt

As the world’s largest carbon emitter, China has been committed to carbon emission reduction and green development. Under the goal of “double carbon”, adjusting the industrial structure and promoting the development of producer services are regarded as effective emission reduction paths. In this paper, from the perspective of market entry of enterprises, we firstly investigate the transmission mechanism between market entry of enterprises and industrial agglomeration and summarize the carbon emission reduction mechanism of producer services. Based on the panel data of 110 prefecture-level cities in China’s Yangtze River Economic Belt (YREB) from 2003 to 2017, we analyze the impact of producer services on carbon emission reduction by using the dynamic spatial panel model. The empirical results show that China’s urban carbon dioxide emissions have noticeable spatial spillover effects and high emission club clustering characteristics and exhibit a noticeable snowball effect and leakage effect in time and space dimensions. The development of the producer services can effectively reduce carbon emission levels, effectively solving the dilemma of “stabilizing growth and promoting emission reduction”. Furthermore, there is an apparent synergistic effect between enterprises’ market entry and industrial agglomeration. The agglomeration of producer services can effectively promote the entry of innovative new enterprises, thus increasing the carbon emission reduction effect. However, due to resource mismatch and isomorphic development, this carbon emission reduction effect has apparent industrial heterogeneity and regional heterogeneity. Finally, this paper makes suggestions for optimizing regional industrial structure, strengthening inter-regional linkage cooperation, and promoting the advanced development of the producer services.

Industrial Co-Agglomeration and Air Pollution Reduction: An Empirical Evidence Based on Provincial Panel Data

Industrial co-agglomeration plays a significant role in the moving up of the manufacturing industry in the value chain and in transforming China from a manufacturing giant into a world manufacturing power. This study establishes a co-aggregation index to explore spatio-temporal changes of the co-agglomeration between manufacturing and producer services in 30 provinces of China from 2004 to 2019. Furthermore, we use spatial Durbin model to analyze the impact of industrial co-agglomeration on air pollution reduction. We find that (1) the co-agglomeration index varies remarkably at spatio-temporal scale; (2) high co-agglomeration index is mainly distributed in eastern and central China, while low co-agglomeration index is mainly located in the western region; (3) the co-agglomeration index presents a cluster pattern among provinces, with the cluster of high value in eastern China and the cluster of low value in western China; and (4) the co-agglomeration between manufacturing and producer services is proven effetely to reduce air pollution, which is accompanied with spatial spillover effect. We also provided policy implications in line with diverse industries, multi hierarchies, and different regions, promoting the coordination of manufacturing and producer services and improving air quality.

Will Digital Inclusive Finance Make Economic Development Greener? Evidence From China

This paper aimed to accurately assess the driving effect of digital inclusive finance (DIF) on green economic growth, better implement DIF-related policies, and promote the development of green economy. Based on the urban panel data from 2011 to 2018 and the DIF index, this paper investigates the impact of DIF on economic green development and its internal mechanism. The results show that there is a significant positive U-shaped nonlinear relationship between DIF and green development. Through the robustness test of the threshold model, instrumental variable model (IV), and system generalized method of moments (SYS-GMM) model, the results are still valid. The mechanism research shows that the DIF can indirectly promote China’s green development by the coagglomeration degree of producer services and optimize and upgrade industrial structure. This study provides policy implications for developing countries around the world to achieve green development by promoting the DIF level.

The Impact of the Opening of Producer Services on the International Competitiveness of Manufacturing Industry

Countries participating in the international division of labor each try to occupy the industrial highlands, obtain competitive advantages, and promote sustainability of economic development. Based on Porter’s Diamond model, it is widely believed that producer services are vital to support the manufacturing industry. Consequently, this paper selects samples of 55 countries and uses data from 2010 to 2017 to empirically test the impact of producer service’s opening on the export competitiveness of the manufacturing industry. The results show that the opening of producer services in a country promotes the improvement of international competitiveness of manufacturing industry, and the improvement effect is more significant in developed countries than in developing countries. Additionally, the negative impact of foreign capital access restrictions on the export competitiveness of the manufacturing industry is greater than the positive impact of service trade opening. It is also found that the restrictions on foreign capital’s opening in the financial sector have the biggest negative impact on manufacturing exports than that of other divisions of the producer service industry. To improve national competitiveness, it is suggested that the integration of service and manufacturing industries should be enhanced and to decrease FDI access to financial and transportation services restrictions.

Producer Services Openness and the Development of Servitization: The Perspective of Two-Way Openness

This paper brings producer services “bringing in” and “going out” into the same analytical framework and explains the influence mechanism of producer services opening on the development of servitization from three aspects of import trade, FDI, and OFDI. On this basis, using the latest input-output data of WIOD, this paper constructs some indicators to measure the openness of producer services such as import trade penetration, FDI penetration, and OFDI penetration and then empirically tests the impact of producer services openness on the development of servitization in China. The results show that the openness of producer services has a significant positive impact on the development of China’s servitization. In addition, the robustness analysis based on variable substitution and different estimation methods shows that the conclusions are robust. The heterogeneity test shows that the impact of producer services openness on servitization has heterogeneity. The specific performance is as follows: there is different impact of producer service sector openness on the development of servitization; the impact of producer service openness on the development of servitization with different factor intensities is also different; and there is also different impact of producer service sector openness on the development of servitization with different factor intensities. The policy implications of these research conclusions are as follows: firstly, taking co-construction of the “Belt and Road” as a chance to promote the new open pattern; secondly, focusing on expanding the openness of high-end producer services; and thirdly, taking innovation driven development as the guide to increase R&D investment of producer services.

A Dynamic Evolutionary Game Model of Collaborative Innovation in Manufacturing Services Industry and Manufacturing Industry

Collaborative innovation has a significant impact on the efficiency of manufacturing services and manufacturing innovation. In this paper, a collaborative innovation model of manufacturing services and manufacturing is constructed based on the two-dimensional asymmetric evolutionary game basic model. The stable evolution strategy of the model is to be found through the solutions to the replicator dynamic differential equation of both sides of the game. The results show that on the one hand, producer services can rely on the carrier of knowledge capital and human capital to link to the manufacturing process from front to back, and form the forward and backward spillover effect. On the other hand, the knowledge elements in producer services, especially tacit knowledge, are transmitted through the modern network under the common industrial culture atmosphere in the process of continuous industrial interaction and industrial integration, which can promote the sharing and transfer of knowledge, produce interactive innovation, and finally promote the innovation of value chain.
