China’s growing trade with countries along the“Belt and Road”Initiative is accompanied by a focus on green development.Based on the panel data from 2007 to 2018,this paper establishes a threshold regression model to empirically analyze the institutional quality threshold effect of China’s foreign trade technology spillover on the GTFP of countries along the“Belt and Road.”The results show that China’s foreign trade technology spillover has a significant institutional quality double threshold effect on the green total factor productivity of the countries along the“Belt and Road.”As the institutional quality of the countries along the“Belt and Road”crosses a specific threshold value,the impact of China’s foreign trade technology spillover on the green total factor productivity of the countries along the“Belt and Road”has a significant positive promoting effect,and corresponding suggestions are put forward. 展开更多

The innovative city pilot policy(ICPP)is an essential manifestation of China’s construction of an innovative and green-driven development country.We incorporated urban green total factor productivity(GTFP)growth into the evaluation of ICPP.Based on the panel data of 223 cities in China from 2005 to 2020,we used the difference-in-differences model to empirically assess the influence and mechanism of the ICPP on urban GTFP growth.The main results show that(i)The ICPP has maintained an effectively fluctuating promotion on urban GTFP growth,mainly manifested in the urban green technological progress improvement.(ii)The ICPP has urban heterogeneity in promoting GTFP growth in pilot cities,mainly affecting key cities such as provincial capitals.(iii)The interaction between the agglomeration of producer services and the ICPP inhibits GTFP growth in pilot cities. 展开更多

The enhancement of industrial green total factor productivity is pivotal for achieving high-quality and sustainable economic development.This study assesses China’s performance using the SBM-GML model,employing province-level panel data spanning from 2004 to 2020.Furthermore,we examine the influence of green finance and technological progress on industrial green total factor productivity using a spatial econometric model.The findings uncover that the relationship between the level of green financial development and industrial green total factor productivity follows a U-shaped curve.Initially,low levels of green financial development exert a suppressive effect on industrial green total factor productivity,proving ineffective in the short term.However,with the progression of green finance development,a positive and significant long-term impact on industrial green total factor productivity emerges.Moreover,technological progress demonstrates a noteworthy promotional effect on industrial green total factor productivity.The analysis delves deeper into revealing that industrial structure and environmental regulation intensity exhibit a significant negative relationship with industrial green total factor productivity.In contrast,both energy structure and education level showcase a substantial positive relationship with industrial green total factor productivity. 展开更多

The National High-tech Zone(NHTZs)is an important strategic platform for cultivating high-tech industries and realizing high-quality economic development in China.Based on the combined data from 2006 to 2014 of the industrial enterprise database,the customs database,and the China Development Zones Audit and Announcement Catalogue(abbreviated asthe Catalogue),this paper systematically investigates the influence of the construction of NHTZs on enterprise’s total factor productivity(TFP).Results show that NHTZs have a positive impact on the TFP of enterprises in the zone,and this conclusion is still valid after considering endogeneity problems.Furthermore,the above productivity effects of NHTZs are heterogeneous in terms of enterprise ownership,external environment and establishment time,and NHTZs have greater stimulation effects on enterprise productivity after comparing with other types of functional zones.An investigation of the specific mechanisms at play shows that NHTZs promote the TFP of enterprises in the zone through the release of preferential policies,strengthening the“technology spillover effects”of imported intermediate goods,enhancing enterprise’s innovation ability and attracting talent.In addition,based on the decomposition of industry productivity,this paper also investigates the impact of NHTZs on changes in industry productivity and finds that NHTZs promote the overall productivity of specific industries mainly by stimulating the productivity improvement of incumbent enterprises and expanding the market share of high-productivity enterprises.Moreover,the preferential policies of NHTZs do not significantly stimulate high-productivity enterprises to enter the zones,nor do they cause low-productivity enterprises to exit.This research is helpful in objectively evaluating the economic effects of the NHTZs in China and in providing a theoretical basis for its further adjustment. 展开更多

Based on the DEA-based Malmquist index method,the total factor productivity was calculated for 5 major banana production areas in 2003-2004,and it was further divided into technological progress and technical efficiency.The results show that the total factor productivity of banana industry in China was 1.3% in the sample period,mainly due to technological progress,the average growth rate was 2.6%,while the pure technical efficiency and scale efficiency was -0.1% and -1.2% respectively.The improvement of total factor productivity in banana industry in China relied mainly on technological progress,cultivation of new banana varieties,management of high quality cultivation,popularization and application of water conservation and fertilizer saving technology,and injury-free picking technologies.The pure technical efficiency and scale efficiency of banana production were negative,indicating that the management level of banana was not high.The effect of scale economy of this industry through agglomeration and consolidation is still to be practiced.Banana growers should promote the improvement of large scale and management level of the banana industry at the same time of promoting the technological progress. 展开更多

Sustained economic growth is a key source of poverty alleviation and growth that is driven more by productivity than the quantity of factors of production is useful for long-term inclusive growth and poverty reduction,which is needed in Sub-Saharan Africa.The paper sought to investigate the relative roles of capital and labour as factors of production and their productivity in the growth process of Sub-Saharan Africa using annual data from 2000 to 2018.A production function was estimated,following the construction of data for capital stock using the perpetual inventory method.The production function was estimated by applying the instrumental variables(IV)to the two-way fixed effects model,using clustered standard errors.The results show that the share of capital and labour in production were 0.14 and 0.86 respectively.Capital,labour and their productivity contributed 24.7%,51.1%and 24.2%respectively to real GDP growth during the period 2001 to 2018.Further efforts in building the productivity of capital and labour are therefore required in Sub-Saharan Africa.Building good governance,the legal framework,political stability,expanded access to quality education and affordable quality healthcare,greater openness towards technological progress are therefore imperative. 展开更多

A critical method of ensuring grain production is to increase the total factor productivity(TFP),and the key measure to increase the TFP of grain production lies in the construction of agricultural public infrastructure.For this topic,existing literature lacks systematic and empirical analysis.Therefore,research on the influence of agricultural public infrastructure on the TFP of China’s grain production has relatively strong policy implications and theoretical value.For this study,we collected panel data for grain inputs and outputs as well as for agricultural public infrastructure in China’s provinces(autonomous regions/municipalities)from 1990 to 2017,and adopted the stochastic frontier function(SFF)approach to measure the TFP of provincial-level grain production.Through this empirical study,we analyzed the influence of agricultural public infrastructures,such as irrigation,roads,and electric power facilities on the TFP of China’s agriculture.We found that such facilities have a positive influence on the TFP of grain production.Specifically,when the input for irrigation facilities is increased by 1 percent,the TFP of grain production will rise by 5.74 percent.Based on this finding,policy recommendations are proposed for enhancing grain TFP through agricultural public infrastructure construction. 展开更多

Although total factor productivity(TFP)is a common concept in mainstream Western economics,its origins are actually embedded in Marx's understanding of improving labor productivity.As an important element of labor productivity under socialized production conditions,TFP is further reflected in the category of"socially necessary labor time"in two distinct senses.Re-examining TFP from the perspective of Marxist political economy and incorporating it into the theoretical system of political economy of socialism with Chinese characteristics vividly illustrates the essence of"adhering to original principles,assimilating foreign concepts,and embracing a forward-looking vision"within political economy of socialism with Chinese characteristics.In practice,it is necessary to start with Marx's theory of productive labor and delineate the sectors involved in productive labor so that TFP and its fluctuations can be measured in a more relevant way.In the context of the new era and the new journey,as the key to achieving high-quality economic development in China,efforts are needed to increase TFP.This requires balancing economic factors such as the long term and short term,supply and demand,and gross quantity and structure,and promoting transformative changes in the quality,efficiency,and dynamism of economic development. 展开更多

This paper improves the estimation of firm-level total factor productivity(TFP)by considering energy use and including small-and medium-sized enterprises using data from the Chinese National Tax Survey Database(2008-2011).It analyzes the production efficiency of Chinese manufacturing firms using the improved TFP data and finds that(i)the TFP data frequently used in previous studies overestimated firms'real production efficiency;(i)the TFP of manufacturing firms decreased from 2008 to 2011 due to declines in both technical efficiency and allocation efficiency,(ii)the lower capacity utilization of production factors led to lower technical efficiency;and(iv)allocation efficiency decreased more in provinces and industries with higher shares of state-owned enterprises.The findings have policy implications for enhancing growth potential in the long run. 展开更多

However, research in the Chinese context is relatively rare. Drawing upon data from the China General Social Survey, our results suggest that the enhancing effect of social capital on total factor productivity is very limited in the case of China. The network dimension of social capital is significant only in pooled OLS estimations, and trust as well as the participation dimension of social capital exert no impact across all estimations. Our interpretation is that this is partly due to the fact that trust, values and norms formed in civil society are inherently difficult to transmit to the market sector. Besides, the impact of social capital on economic performance is undermined when physical capital plays a significant role in production. We therefore propose that the effect of social capital on economic performance is contingent on localized social and economic conditions. 展开更多

In different economic periods,if the government blindly adopts expansionary fiscal policy,it may not be able to effectively increase total factor productivity(TFP).Based on this,this paper constructs a factor augmented vector autoregressive model with time-varying parameters and stochastic volatility(SV-TVP-FAVAR),and explores the nonlinear shock effect of China’s fiscal policy on TFP from the dual perspective of aggregate and structure.The study finds that:(1)At the aggregate level,the increase in fiscal expenditure in each period has a signifi cant inhibitory effect on TFP,while the increase in fiscal revenue has a significant promotion effect on TFP;(2)At the structural level of expenditure,in the period of economic depression and high economic growth,the increase in investment expenditure,education expenditure,technology expenditure,and public service expenditure all have a strong incentive effect on TFP,but the increase in science and technology and education expenditure in the period of economic stability has not effectively improved TFP;(3)At the structural level of tax,the increase in commodity tax,including consumption tax,value-added tax,and tariff,and individual income tax will signifi cantly inhibit the increase in TFP,but the increase in corporate income tax can signifi cantly increase TFP.Therefore,under the new economic normal,policy makers should build a two-wheel driven fiscal policy of“aggregate regulation and structural optimization”to optimize the structure of fiscal expenditure and taxation,and promote high-quality economic development. 展开更多

Weiyuan shale gas play is characterized by thin high-quality reservoir thickness,big horizontal stress difference,and big productivity differences between wells.Based on integrated evaluation of shale gas reservoir geology and well logging interpretation of more than 20 appraisal wells,a correlation was built between the single well test production rate and the high-quality reservoir length drilled in the horizontal wells,high-quality reservoir thickness and the stimulation treatment parameters in over 100 horizontal wells,the dominating factors on horizontal well productivity were found out,and optimized development strategies were proposed.The results show that the deployed reserves of high-quality reservoir are the dominating factors on horizontal well productivity.In other words,the shale gas well productivity is controlled by the thickness of the high-quality reservoir,the high-quality reservoir drilling length and the effectiveness of stimulation.Based on the above understanding,the development strategies in Weiyuan shale gas play are optimized as follows:(1)The target of horizontal wells is located in the middle and lower parts of Longyi 11(Wei202 area)and Longyi 11(Wei204 area).(2)Producing wells are drilled in priority in the surrounding areas of Weiyuan county with thick high-quality reservoir.(3)A medium to high intensity stimulation is adopted.After the implementation of these strategies,both the production rate and the estimated ultimate recovery(EUR)of individual shale gas wells have increased substantially. 展开更多

To address air pollution and offer a convenient and comfortable living environment,the Chinese government launched a smart city pilot(SCP)project in 2012,accompanied by a comprehensive set of environmental and energy-related laws and regulations.Although academic interest in smart cities has surged,there remains a notable gap in empirical research exploring the economic,environmental,and energy effects of such initiatives.Taking 232 prefecture-level cities from 2003 to 2017 as research subjects,this study measures energy effi‐ciency by using energy consumption per unit of GDP and adopts a difference-in-differences(DID)analysis to investigate the impact of SCPs on energy efficiency.The empirical results indicate that SCPs improved energy efficiency by promoting urban technological innovation capabilities and green total factor productivity,and this effect was more pronounced in cities that were more dependent on traditional fossil fuel energy sources and had more developed fiscal and financial levels.Studying the impact of smart city construction on energy utilization efficiency in developing countries,such as China,is not only significantly enlightening for China’s green and low-carbon transition but also provides reference opinions for constructing smart cities and the path to enhancing energy efficiency in other developing countries.The findings provide valuable insights into the global development of smart cities,urban sustainability,and high-quality economic growth. 展开更多
