| In recent years,the rapid development of China’s economy has been accompanied by increasingly severe environmental problems.As the world’s largest carbon emitter,China has made commitments to the world to achieve carbon peaking by 2030 and carbon neutrality by2060,which clarifies China’s green development goals and expresses China’s role as a responsible determination of a great power.However,the construction industry,one of the pillar industries of China’s economy,has become an obstacle to China’s comprehensive green development due to the problems of high energy consumption,high pollution and high emissions.With the continuous improvement of the urbanization rate,the construction industry will face the problem of balancing the urbanization process with resources and environmental protection for a long time in the future.The report of the 19 th National Congress of the Communist Party of China pointed out that promoting green development,accelerating the establishment of legal systems and policy guidance for green production and consumption,and establishing and improving an economic system for green,low-carbon and circular development are important measures to build a beautiful China.In other words,government-led environmental regulation is an important instrument to solve the problem of green development at this stage.Therefore,it is of great practical significance to explore how to use environmental regulation to better promote green construction.The green construction has long been a topic of general concern to scholars.Environmental regulation,as an important means formulated by the Chinese government to solve environmental problems,has gradually attracted scholars’ attention in recent years.However,the relationship between environmental regulation and green construction has not been fully explored.First,previous studies mostly focus on traditional environmental regulations(command-and-control,market-based,and informal),and less research has been done on some types of environmental regulation that have been gradually popularized in recent years,such as demand-side environmental regulation and fuzzy environmental regulation.Second,most of the previous studies on the green construction focused on a single perspective,and lacked a more comprehensive and systematic exploration.Third,even though there are many studies in the background of China,the impact of some important factors such as characteristics of system and construction industry on the effectiveness of environmental regulation is still ignored.Based on the above research gaps,taking institutional theory as the overall theoretical framework,this study integrates five types of environmental regulations and explores the impact of environmental regulations on green construction from the micro and macro perspectives as well as the two perspectives of project management and provincial analysis.This study consists of three main research contents:First,the impact of environmental regulations on project manager’s green engineering project management behavior(Chapter 3).Based on in-depth interviews with project managers,a theoretical model of the relationship between project managers’ perception of traditional environmental regulations and green engineering project management behavior was established.The mediation effect of project managers’ affective commitment to change and the moderating effect of cost,time and quality constraints were considered in the model.A questionnaire survey was conducted among 129 project managers to obtain the data,and regression analysis was used to test the theoretical model.Second,the impact of environmental regulations on green total factor productivity of construction industry(Chapter 4).Based on Porter’s Hypothesis,the relationships between traditional and demand-side environmental regulations and total factor productivity of construction industry were hypothesized and a theoretical model was established.The moderating effect of regional policy conflict and industry nationalization degree was considered in the model.The provincial panel data from 2008 to 2017 were obtained from various statistical almanacs and the website of the National Bureau of Statistics.The green total factor productivity was calculated using the data envelopment analysis(SBM-DEA)model based on slack variables,and the theoretical model was tested by regression analysis method.Third,the impact of environmental regulation on the carbon emission intensity of the construction industry(Chapter 5).Based on the fuzzy characteristics of the policy tools of fuzzy environmental regulation,the implementation mechanism of its carbon reduction in the construction industry is analyzed with the method of case study.Based on the results of implementation mechanism and previous studies,the relationship between fuzzy environmental regulation and carbon emission intensity of construction industry is hypothesized and a theoretical model is constructed.Provincial panel data from 2008 to 2017 were collected from the Statistical Yearbook and the website of the National Bureau of Statistics,and the theoretical model was tested using the PSM-DID method based on propensity score matching.The main conclusions of this study are as follows.First,project managers’ perception of traditional environmental regulations indirectly improves their green engineering project management behavior through the mediating variable of affective commitment to change.Cost constraint negatively moderates the relationship between perceived traditional environmental regulations and affective commitment to change.Time constraint plays a negative moderating role in the relationship between affective commitment to change and green engineering project management behavior.Secondly,both traditional environmental regulations and demand-side environmental regulation can improve the green total factor productivity of construction industry.Regional policy conflict plays a negative moderating role;the degree of industry nationalization has a negative moderating effect on the traditional environmental regulations and a positive moderating effect on the demand-side environmental regulation.Third,fuzzy environmental regulation implements an implementation mechanism that intersects the horizontal support path and the vertical support path for carbon reduction in the construction industry.And it can effectively reduce the carbon emission intensity of the construction industry.This study constructs a multi-level and multi-perspective research framework of environmental regulations’ impact on green construction,which is conducive to improving the perspective of the green development of the construction industry and strengthening the understanding of the effectiveness differences of environmental regulation at different levels.The first part of the research is based on the Theory of Organizational Change,and explores the transformation process of project managers’ thoughts and behaviors from the perspective of organization,which expands the research perspective of project management.The second part of the research is based on the characteristics of China’s institutional environment and construction industry,and puts forward the view that influencing factors(regional policy conflict,industry nationalization degree)will affect the effectiveness of environmental regulation,and increases the knowledge of environmental regulation and green construction.In the third part,the theoretical model is tested by quantitative research method,and the implementation mechanism of fuzzy environmental regulation is explored by qualitative research method.This research paradigm combining qualitative and quantitative research makes up for the limitations of previous quantitative research in fuzzy policy research.The results of this study can be used as a reference for policy makers,regulators and construction enterprises to make joint efforts to further promote green construction. |
