Will Network Infrastructure Optimization Make Manufacturing Enterprises "Out of Real to Virtual"? --- A Quasi-Natural Experiment from the "Broadband China" Policy

Manufacturing is the most important component of the real economy, and the application of modern network information technology can effectively improve the operational efficiency of manufacturing enterprises. In the context of "Made in China 2025", it is particularly important to prevent manufacturing enterprises from deviating from their main business and becoming excessively financialized. Maintaining the essential business activities of manufacturing enterprises is of great importance to China's economic development. Based on the operating data of all A-share listed manufacturing companies from 2010 to 2020 and combining the "Broadband China" demonstration city policy, this paper uses a multi-point double-differenced model to explore the relationship between network infrastructure optimization and excessive financialization of manufacturing enterprises. The research shows that: 1) Network infrastructure optimization will make manufacturing enterprises increase their financialization level, and this effect is mainly manifested through optimizing accounts receivable management. 2) From the perspective of enterprise size, compared with small and medium-sized manufacturing enterprises, large manufacturing enterprises are more likely to improve their financialization level through network infrastructure optimization. 3) From the perspective of the degree of diversified operations, manufacturing enterprises with high diversified operations are more likely to take advantage of network infrastructure to improve their financialization level. This study provides reference and guidance for later researchers on the impact of "new infrastructure" represented by network infrastructure construction on the business model of manufacturing enterprises.

How Does Network Infrastructure Construction Affect Livestock Carbon Emissions?

Against the backdrop of new carbon peak and carbon neutrality targets, China must address livestock carbon emissions (LCEs), which account for the largest proportion of agricultural carbon emissions in China. China has been promoting network infrastructure construction (NIC) for digital transformation. This study explores whether NIC can affect LCEs. To capture the potential effects of NIC, a conceptual framework is constructed originally and its impacts on LCEs are tested empirically through a two-way fixed effect model. The results show that NIC can significantly reduce LCEs. The results hold steady in various robustness checks, and the impacts express heterogeneities across provinces with different LCE levels, NIC levels, and regions. Mechanism analysis reveals that NIC can increase LCEs through the livestock industry scale effect, which is nevertheless outweighed by technological innovation and factor allocation’s reduction effects triggered by NIC. Additionally, transportation infrastructure construction serves a moderating role by reinforcing the reduction effect of NIC on LCEs. The conclusions are crucial for advancing the understanding of NIC’s potential benefits and policymaking for carbon emissions reduction in China.

Network Infrastructure Construction and River Pollution: Evidence from the Broadband China Strategy

Can network infrastructure construction improve the low-carbon innovation of Chinese enterprises?

This study considers the implementation of the "Broadband China" strategy as an exogenous policy shock and examines the impact of network infrastructure construction (NIC) on the low-carbon innovation (LCI) of enterprises and its underlying mechanisms by using a progressive difference-in-difference model based on the data of Chinese listed enterprises from 2009 to 2020. This study finds that NIC can improve the LCI of enterprises. After the elimination of the sample selection bias and selection of the urban slope as the exogenous instrumental variable, the conclusions remained robust. The results of the mechanism test show that upgrading the human capital level, reducing transaction costs, and alleviating financing constraints are the three important paths through which NIC can help enterprises improve their LCI level. The heterogeneity analysis determines that NIC has considerable comparative advantages for enterprises with executives who have a financial background and enterprises with high knowledge stock. In addition, LCI improvement can further enhance enterprise value. The research conclusions can broaden the microscopic research perspective of enterprise transformation and upgrading theory and provide reliable empirical evidence for China's low-carbon economic transformation.

The Effect of Digitalization on Ambidextrous Innovation in Manufacturing Enterprises: A Perspective of Empowering and Enabling

Digital transformation has become an inevitable choice for manufacturing enterprises to sustain innovation in the digital world. This study selected a sample of Chinese provinces and A-share companies listed on the Shanghai and Shenzhen stock markets from 2011 to 2021 to examine the relationship between regional digitalization, enterprise digitalization, and enterprise ambidextrous innovation. We found that (1) regional digitalization can promote exploitative and exploratory innovation of manufacturing enterprises. Digitalization plays an empowering effect in the promotion process. The regional digital talent reserve significantly impacts ambidextrous innovation in manufacturing enterprises more than network infrastructure construction, digital technology development, and digital technology application; (2) Enterprise digitalization can promote exploitative and exploratory innovation of manufacturing enterprises. Digitalization plays an enabling impact in this promotion process; (3) Regional digitalization can promote the level of manufacturing enterprise digitalization. In promoting enterprise ambidextrous innovation, digitalization can realize the transformation from regional digitalization empowering to enterprise digitalization enabling. The regional digital talent reserve significantly impacts manufacturing enterprise digitalization more than network infrastructure construction, digital technology development, and digital technology application; (4) The impact of regional and enterprise digitalization on exploratory innovation in large-scale manufacturing enterprises is more significant, and large-scale enterprises are better able to transform from digitalization empowering to enabling. The conclusions of this study have specific theoretical and practical significance for revealing the relationship between digitalization and enterprise ambidextrous innovation and then promoting regional digitalization development, manufacturing enterprise digital transformation, and innovation development.

All-for-One Tourism Demonstration Zones and High-Quality Development of Tourism: Evidence from the Quasi-Natural Experiment in China

The all-for-one tourism guides the development of the tourism industry in China and promotes coordinated development of the economy and society. Existing studies emphasize the significance of all-for-one tourism but pay limited attention to the impact and mechanism of all-for-one tourism on the high-quality development of tourism. By employing the all-for-one tourism demonstration zones as a quasi-natural experiment, this research uses the time-varying difference-in-differences (DID) model to empirically investigate the relationship between all-for-one tourism demonstration zones and the high-quality development of tourism. In particular, under the guidance of the new development philosophy, this research constructs a measurement and evaluation indicator system for the high-quality development of tourism from five dimensions, including innovative, coordinated, green, open, and shared development. The results show that the all-for-one tourism demonstration zones positively impact the high-quality development of tourism, and the result is robust to a series of robustness checks, including the placebo test and the propensity score matching (PSM) procedures. Network infrastructure construction and tourism talent agglomeration are mechanisms channelling through all-for-one tourism demonstration zones and high-quality tourism development. Heterogeneity analysis reveals positive impacts of all-for-one tourism demonstration zones on central and western regions and provinces with a low proportion of tertiary sector.

Does network infrastructure construction reduce energy intensity? Based on the “Broadband China” strategy

As one of the new economic forms, the digital economy has penetrated into all sub-sectors of the economy becoming a new engine for economic growth. Network infrastructure is the pillar and core driver for the development of the digital economy, getting increasingly evident and important. Meanwhile, green development has become a time trend for the more and more serious global climate problems. Thereinto, reducing energy intensity is an important starting point for achieving green development. The impact of network infrastructure on energy intensity should not be ignored. This article uses the “Broadband China” demonstration cities as a quasi-natural experiment to reflect the improvement of network construction and build a time-varying difference-in-differences (time-varying DID) model to explore the impact of network construction on Chinese prefecture-level energy intensity. The results show that: (1) The construction of network infrastructure can significantly reduce prefecture-level energy intensity, and this conclusion still holds after a series of robustness tests. (2) Network infrastructure construction will reduce prefecture-level energy intensity through the mediating effect of energy efficiency, market environment, and innovation. (3) The effect will be more obvious in Northeast China, with huge scale, high levels of human capital, perfect broadband user access, complex industrial structures and better financial development levels. We hope this research provides empirical evidence for improving the construction of network facilities and realizing the “Two-Wheel Drive” of digitizing and greening.

The Path to Low Carbon: The Impact of Network Infrastructure Construction on Energy Conservation and Emission Reduction

Energy conservation and emission reduction are important ways to cope with global warming. An analysis of energy conservation and emission reduction from the perspective of network infrastructure construction provides an important perspective for the study of sustainable development. Based on the research sample of 263 cities in China from 2006 to 2019, and taking the policy of “Broadband China” as a quasi-natural experiment, this paper uses the double difference model to evaluate the impact of network infrastructure construction on energy conservation and emission reduction. The results show that (1) the construction of network infrastructure can significantly improve the energy utilization rate and reduce carbon emissions intensity, which helps to promote energy conservation and emission reduction. (2) From the perspective of a functional mechanism, on the one hand, network infrastructure construction affects energy conservation and emission reduction through micro-mechanisms such as green technology innovation and energy efficiency. On the other hand, network infrastructure construction also drives the development of the Internet and the digital economy, and promotes energy conservation and emission reduction through macro-mechanisms such as industrial structure and financial development. (3) The heterogeneity analysis shows that network infrastructure construction in non-resource-based cities, eastern regions and low-carbon cities has a greater impact on energy conservation and emission reduction. This study provides a new perspective for achieving low-carbon development goals.

The effects of government support on enterprises' digital transformation: Evidence from China

AbstractDigital transformation has become a general trend for enterprises, and it is necessary to investigate the impact of government support on enterprises' digital transformation from the perspective of policy instruments. But so far, there is less empirical evidence on their relationship. Based on Chinese firm‐level data, we investigate the effects of government subsidies and tax incentives on enterprises' digital transformation. The results show that two forms of government support both positively promote enterprises' digital transformation. Moreover, we analyze which factors mediate the observed effects. We demonstrate that easing financial constraints, increasing Research and Development (R&D) investment, and improving risk‐taking ability are underlying mechanisms. Heterogeneity analysis indicates that enterprises that are non‐state‐owned, with higher technology level and higher absorptive capacity, have higher digital transformation. The higher the level of digital finance development and network infrastructure construction in a region, the greater the positive effect of government support on enterprises' digital transformation. The results provide clearer guidance for governments to provide government support so as to stimulate enterprises' digital transformation.

Can low‐carbon development force enterprises to make digital transformation?

AbstractEnterprises need to innovate business strategies to deal with the negative effects of low‐carbon development, among which digital transformation is an important breakthrough technology. This paper discusses the impact of low‐carbon development on enterprises' digital transformation. Theoretical analysis shows that environmental regulations driven by low‐carbon development have the compensatory effect of stimulating enterprise digital transformation to mitigate misallocation of capital and labor, especially for enterprises with higher productivity. In addition, both the construction of network infrastructure and the development of digital finance can strengthen the incentives for enterprises' digital transformation. The empirical tests based on Chinese A‐share listed enterprises show that the degree of enterprises' digital transformation increases by 0.0122 standard deviation for every one standard deviation reduction in regional carbon emission intensity. These results deepen the understanding of the relationship between green development and microenterprise digitalization.

Can Network Infrastructure Construction Alleviate Corporate Financing Constraints?

T The construction of network infrastructure is conducive to promoting enterprises to ease financing constraints, which is of great practical significance for optimizing the allocation efficiency of enterprise factors and promoting high-quality economic development. Based on the perspective of information asymmetry, taking the "Broadband China" pilot as a natural experiment, using the data of Chinese listed companies from 2009 to 2020, and using the multi-period double difference method to empirically test the impact of network infrastructure construction on the constraint level of enterprise financing and verify its internal mechanism. The study found that the construction of network infrastructure helps to alleviate the financing constraint level of enterprises. Heterogeneity analysis shows that the policy significantly alleviates the financing constraints of large-scale enterprises, but the impact on small and medium-sized enterprises is not significant. The conclusions of this paper not only broaden the perspective of "new infrastructure" research, but also provide reliable empirical evidence and policy implications for the impact of network infrastructure construction on micro-enterprise behavior.

The Impact of Internet Development on Urban Eco-Efficiency-A Quasi-Natural Experiment of "Broadband China" Pilot Policy.

Based on the panel data of 285 prefecture-level cities and above in China from 2005 to 2019, this paper takes the “Broadband China” pilot policy as a quasi-natural experiment and evaluates the impact of Internet development on urban eco-efficiency (symbolized by the “Broadband China” policy) by constructing multi-period difference-in-difference (DID) and spatial DID models. Results show that: the “Broadband China” pilot policy significantly improves the urban eco-efficiency: the eco-efficiency in pilot cities is about 16.8% higher than that in other cities. The results remain consistent after testing for robustness, including using estimation methods, excluding the sample of key cities, changing core explanatory variables, and introducing instrumental variables. Next, the influence of the “Broadband China” pilot policy on eco-efficiency is characterized by significant regional heterogeneity: Internet development significantly improves the eco-efficiency in the central, eastern and northeastern regions that are economically more developed and not resource-dependent. In contrast, this effect is not obvious in the western region that is economically less developed and resource-dependent. Moreover, the influencing mechanism of Internet development on eco-efficiency suggests that the “Broadband China” strategy boosts urban eco-efficiency by increasing the Internet penetration rate, improving technological innovation capacity, and upgrading the industrial structure. In addition, results from the spatial DID models indicate that the “Broadband China” pilot policy improves the eco-efficiency in local cities and significantly enhances that in neighboring cities. Based on this, this paper puts forward some suggestions regarding promoting new network infrastructure construction and differentiating development policies to fit local conditions.
