A Study On The Impact Of New Infrastructure Construction On Residents’ Well-being

In recent years,new infrastructure construction has become one of the national key strategic development directions.General Secretary Xi Jinping emphasized: "In today’s world,information technology innovation is changing with each passing day,digitalization,networking and intelligence are developing in depth,and it is playing an increasingly important role in promoting economic and social development,modernizing the national governance system and governance capacity,and meeting people’s growing needs for a better life." With the further expansion of investment in new infrastructure construction,new infrastructure such as 5G and artificial intelligence has entered the public life and is closely related to residents’ happiness.Therefore,it is of great significance to explore and quantify the construction level of new infrastructure and residents’ happiness level,systematically analyze its current situation,investigate its evolution trend,and clarify the influencing factors and influencing mechanism of new infrastructure construction on residents’ happiness,to accelerate the construction of new infrastructure and to enhance residents’ happiness,sense of gain and safety.In this context,starting from the definition of new infrastructure construction,21 indicators were selected to build an index system to quantify the level of new infrastructure construction,and the status quo of new infrastructure construction was analyzed by descriptive statistical analysis and kernel density estimation.Based on the data of China Household Tracking Survey(CFPS)from 2014 to 2020,the happiness level of residents was quantified,and descriptive statistical analysis was conducted by urban and rural areas and regions.Ordered Logit model was used to conduct regression analysis of the effect of new infrastructure level on residents’ happiness level.The possible endogeneity was studied by using two-stage least square method,and the results were tested for robustness and heterogeneity.Analyze whether economic level,social equity,consumption level,government public service and Internet use can be used as channels for the new infrastructure level to affect residents’ happiness.The results show that the level of new infrastructure construction is different in the whole country,provinces and regions,and the phenomenon of multilevel differentiation is weakening,and the development trend is good.In the four years from2014 to 2020,residents’ happiness level was generally high,and the proportion of residents’ happiness level was high among all regions and between urban and rural areas,showing a gradually decreasing trend from east to west.The level of new infrastructure has a significant positive impact on residents’ happiness.Among them,the impact on female residents is greater than that on male residents,the impact on residents’ selfrated social status is greater than normal,and the impact on young people is greater than that on middle-aged and elderly people.Economic level,social equity,consumption level,government public service and Internet use are the main factors that affect the new infrastructure level on residents’ happiness.The new infrastructure level can have an impact on residents’ happiness through the above ways.To improve residents’ happiness,the government needs to further expand the development of new infrastructure,accelerate digital construction and narrow the gap between urban and rural construction.
