This paper develops a macro examination framework for simultaneously testing the incentive effect and uncertainty effect under R&D-based growth theory. A stochastic frontier innovation model with heterogeneity has been established and estimated, in which the exogenous cites’ demand changes measured by market potential increases induced by China’s high-speed rails are introduced into both inefficiency mean equation and inefficiency variance equation. The empirical results show that market potential has significantly negative correlation with inefficiency mean and inefficiency variance, which are robust to various market potential measurement, as well as robust to DID setting and IV regressions. The study provides the first macro evidence for supporting both Schmookler hypothesis and Myers-Marquis hypothesis, and the examination framework has obvious advantages over the previous FG framework.

The logistics industry around the world has proliferated over recent years as a large number of business organizations have come to recognize the importance of logistics. Cost control used to be emphasized to remain competitive, but recently green logistics has gained attention with the awareness of the integration of economy and society as a whole. Nowadays, green logistics is a useful concept to improve the sustainability of logistics operations, and its related policies and theoretical research have been investigated and explored. However, the practical applications of green logistics are impeded by real-time data sharing, which is common in the logistics industry. Blockchain technology is adopted to address this challenge and enable data sharing among related stakeholders. This paper presents a reference framework for green logistics based on blockchain to reach the sustainable operations of logistics, with the integration of the Internet of Things and big data. Finally, potential benefits and limitations are analyzed when implementing this framework.
