Environmental regulations (ERs) that can stimulate technological innovation (TI) are the key to enabling a win-win strategy that benefits both economic development and environmental protection. This study seeks to analyze the impacts of ERs on TI. Previous literature highlighted that the black box of TI can be decomposed into technology investment and technology transformation, but empirical studies on such a decomposition have largely been ignored. Moreover, a detailed discussion of the links between ERs and the decomposed components of TI has not been conducted in developing countries such as China. Our study attempts to address these research gaps by (i) decomposing TI using a novel data envelopment analysis (DEA) procedure and further analyzing the impacts of ERs on the decomposed components of TI and (ii) applying this novel methodology to Chinese context. Accordingly, this study is conducted in two stages. First, a novel application of the slack-based measure Network DEA model is developed to uncover the black box of TI using Chinese data in order to estimate the overall efficiency of technological innovation (TIE) and to decompose it into the efficiency of technology investment (TVE) and the efficiency of technology transformation (TTE). Second, a random effect Tobit model is applied to (i) investigate both the linear and nonlinear impacts of ERs on TIE in all sectors and (ii) examine whether the impacts of ERs on TVE and TTE in different subprocesses are heterogeneous or not. Our results have showed the benefits of decomposing TI: while technology transformation in China closely follows the trend of TI, the trend of technology investment is somewhat different. The estimation results further indicate that the impacts of ERs on TIE are nonlinear. Besides, ERs have heterogeneous impacts on the decomposed components of TI. The impacts of ERs on TVE are nonlinear, whereas the impacts of ERs on TTE are statistically insignificant.
Abstract. In the 21st century human society has been developing rapidly which also brings the threat of resource depletion, serious environmental pollution and ecological imbalance. As a pillar industry of the national economy, manufacturing industry has created much material wealth for the society, while at the same time consumed large amount of resources, resulting in greater environmental pollution. Thus, in view of the environmental impact and optimizing the use of resources, the establishment of the so-called "green" supply chain and the implementation of green supply chain management in the manufacturing supply chain are important means to achieve green manufacturing. Green supply chain management is an effective way to solve the conflict between manufacturing industry and environment from the view of system and integration. This paper briefly introduces concept and nature of green supply chain, establishes the conceptual model of green supply chain, analyzes the goal of green supply chain management, and discusses the basic principle and nature of green supply chain management from the idea of sustainable development.
With the accelerating the pace of tobacco control legislation step by step, innovation is the primary driving force for development and we should pay attention to the construction of ecological civilization and unswervingly. In this context, tobacco production enterprises must carry out innovation activities. Based on the theory of value creation, this paper studies the relationship between the path of tobacco production enterprise innovation activities and enterprise value and the dynamic evolution process of enterprise innovation activities under the effect of environmental regulation from the perspective of theoretical deduction. The purpose is to provide an important reference for the choice of enterprise innovation activities, and at the same time enrich the theoretical research on the consequences of environmental regulation and the influencing factors of enterprise value. First, according to the process of value creation, the source of innovation results and the choice of strategies are studied to provide theoretical support for the primary link of tobacco production enterprise innovation activities. Second, study the application product types of innovation achievements and provide the selection basis for the important links of tobacco production enterprise innovation activities. Third, from the perspective of evolutionary economics, the equilibrium dynamic evolutionary game process between government environmental regulation and tobacco production enterprise innovation efficiency and innovation effect is discussed.
