In the era of the digital economy (DE), technology factors and data factors, like a two-wheel drive, have not only redefined the mode of production but also innovatively reshaped production relations. To examine how the DE can ensure food security (FS) in China, this study explores the negative impacts of land resource mismatch (LRM) on FS, the mechanisms of the impacts, and the critical role played by the DE in mitigating its negative impacts, based on China’s provincial-level panel data from 2011 to 2022. This study finds that, first, LRM leads to a reduction in food production, which, in turn, threatens FS, and this conclusion remains robust after a series of robustness tests. Second, the heterogeneity analysis finds that LRM has a greater negative impact on FS in regions with high urbanization levels, regions with a short tenure of officials, and regions that are not major food-producing regions. Finally, in a further analysis, the specific channels and solution paths of the negative impact of LRM on FS are explored in depth. LRM negatively affects the material base and production capacity of food production, including reducing the supply of land, labor, and capital factors for food production; the DE reduces the negative impact of LRM on FS through the use of digital technology and open government data.

Abstract

Software Defined Networking (SDN) has brought many changes in terms of the interaction processes between systems and humans. It has become the key enabler of software defined architecture, which allows enterprises to build a highly agile Information Technology (IT) infrastructure. For Future Sustainability Computing (FSC), SDN needs to deliver on many information technology commitments—more automation, simplified design, increased agility, policy-based management, and network management bond to more liberal IT workflow systems. To address the sustainability problems, SDN needs to provide greater collaboration and tighter integration with networks, servers, and security teams that will have an impact on how enterprises design, plan, deploy and manage networks. In this paper, we propose FS-OpenSecurity, which is a new and pragmatic security architecture model. It consists of two novel methodologies, Software Defined Orchestrator (SDO) and SQUEAK, which offer a robust and secure architecture. The secure architecture is required for protection from diverse threats. Usually, security administrators need to handle each threat individually. However, handling threats automatically by adapting to the threat landscape is a critical demand. Therefore, the architecture must handle defensive processes automatically that are collaboratively based on intelligent external and internal information. Full article
