Research on the Impact of China’s Foreign Trade Technology Spillover on Green Total Factor Productivity of Countries Along the“Belt and Road”:Based on the Institutional Quality Threshold Effect

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.

Effect of China’s technology spillovers on energy intensity in Africa

Empirical studies on the effects of China-African economic relations on energy intensity in Africa are scarce.To fill the gap in the literature,this study investigates the technology spillover effects of the China-Africa trade and investment relations on energy intensity.It uses both linear and nonlinear dynamic panel estimation methods for 42 African countries from 2003 to 2015.The results show that China's technology spillover through imports significantly reduces energy intensity in Africa.The findings are consistent across specifications and sample groups.Moreover,the technology spillover coming from foreign direct investment(FDI)improves energy intensity,particularly in lower-middle-income African countries.The dynamic threshold estimation results show that countries'absorptive ability is important for technology spillover effects of FDI and imports on energy intensity.The results suggest that countries'absorptive capacity should be increased to maximize the benefits of trade and investment technology spillovers.

Technology Spillover and Licensing Strategy of Patentee

The optimal license proportions with and without technology spillover are analyzed with a game-theoretical approach when a patent-holding firm licensed non-drastic process innovation to his incumbent rivals by means of a first price sealed bid auction. The optimal strategy is obtained through solving the game by backward induction. It is found that the range of optimal license proportion is narrower when there is spillover compared to the no spillover case.

Inter-industry Technology Spillover Effects in China:Evidence from 35 Industrial Sectors

The present paper calculates 35 industrial sectors similarity matrices for the period of 1997-2008 using China s input-output tables for 1997, 2002 and 2007, and uses these to measure inter-industry technology spillover to analyze the spillover effects on industrial sectors lahor productivity. The empirical analysis shows that inter-industry technology spillover has a significant positive effect on the labor productivity of each industry. The elasticity of productivity effects of inter-industry technology spillover is not only larger than that of direct R＆D input, but also increases over time. We group the industries into four major categories and find that the inter-industry technology spillover effect within the categories is, on average, greater than that between the four categories, indicating that technology spillover occurs more easily between similar industries. This research shows that the interindustry technology spillover effect in China has begun to increase, and the government should take advantage of this effect.

Do High-technology Exports Cause More Technology Spillover in China?

The volume of China＇s high-technology exports has grown sharply since the implementation of its export promotion strategy ＂Revitalizing Trade through Science and Technology＂ in 1999. This paper investigates whether technology spillover effects are greater for hightechnology exports than for primary manufactured goods exports. We present a generalized multi-sector spillover model to identify both between-spillover effects from exports towards non-exporters and within-spillover effects among export sectors. Using panel data for 31 provinces in China over the period from 1998 to 2005, we find that although high-technology export sectors have higher productivity compared with other sectors, this productivity advantage does not lead to technology spillover to both domestic sectors and other export sectors, and export technology spillover mainly derives from traditional export sectors rather than high-technology export sectors. As such findings can be largely attributed to the fact that China ＂s high-technology exports depend significantly on processing trade byforeign- invested firms, policy implications are discussed in relation to how to best promote the role of China ＂s highechnology exports during economic expansion.

Tech no logy Gap,Reverse Technology Spillover and Domestic Innovation Performanee in Outward Foreign Direct Investment:Evidenee from China

This research adds to the literature studying the effects of outward foreign direct investment(OF DI)on domestic innovation performance and the moderating effect of a technology gap between host and home countries.New definitions of observed technology gap and expected technology'gap are proposed.An observed technology gap captures the existing differences in technology level between establishments,regions or countries.An expected technology'gap is an indication of the effort of imitating and learning from technology leaders.The corresponding measures and effects of observed and expected technology gaps on OFDI-induced reverse technology spillover are analyzed.OFDI in developed countries promotes innovation performance.However,OFDI in emerging markets hampers innovation performance.It is also found that regions with a wider observed technology^gap and a narrower expected technology gap can benefit more from OFDI.

Low-carbon technology innovation responding to climate change from the perspective of spatial spillover effects

China's technological efforts to tackle climate change have lasted for many years. It is necessary to test the effect of these efforts with quantitative method. To be exact, whether and how China's low-carbon technology innovation responds to climate change should be tested. Based on the2004-2015 panel data of 30 provinces in China, we use the method of ESDA analyzing the spatial correlation of China's low-carbon innovation technology. Furthermore, we use the spatial Durbin model empirically analyzing the spatial spillover effects. The results obtained are as follows: first,supply and demand of Chinese low-carbon innovation has some deviation in the spatial distribution. The low-carbon technology innovation as the supply factor shows the characteristics of expanding from the east to the west. Innovation in eastern China has always been the most active, but innovative activities in the middle and western China are gradually decreased.However, carbon emissions have the characteristics of moving westward, implying the change of technology demand different from technology supply. Second, China's low-carbon innovation actively responds to the trend of climate change, indicating China's technological efforts have paid off. However, the spatial spillover effects are not significant, showing that the efforts in each region of China still work for himself. Third, environmental regulation and market pull are important factors for low-carbon technology innovation. Among them, both supporting policy and inhibitory policy have significant impact on the local low-carbon technology innovation, but no significant spatial spillover effects. It shows that environmental policies in different regions are competitive and lack of demonstration effects. Economic growth and export as market pull have higher level of effect on low-carbon technology innovation for both local and adjacent areas.Some policy implications are proposed based on these results finally.

Technological Capacity and Technology Catching-Up for Regulatory Mechanism of Sharing Economy Enterprises

Sharing economy developed soon in China recently.On the basis of analyzing technology spillover between a technologically advanced nation(country)and a less developed one,a technology catching-up model of technological capacity and path dependence is proposed based on Verspagen mode.The proposed model can explain how a less developed nation(country)can catch up the advanced one.It is not only to improve its own technological capacity,but also whether it could bread“the locking”of path dependence.For the less developed nation(country),the“conscious behavior”of economic body cannot be ignored to achieve the evolution from path dependence to path creation.Thus,the less developed nation(country)should cultivate the technology ability,furthermore,the creative realization and ability,which could break away the negative impact of technology to path dependence,and catch up the advanced one.

广义道德论:当代科技道德的重塑

当代科技既超现实又反现实,在建构世界的同时又对真实世界实现了“降维打击”。探讨当代科技发展趋势如人工智能、生物医学、基因编辑、量子科技等,需要明确其中蕴含的当代性。所谓当代科技发展之“发展”有双关深意:既生成了新兴技术的道德问题本身,又生成了可解方案——广义道德论。新技术的溢出突破道德解释的理论极限,需要创设一种能够将“包容性”和“适应性”统合起来的新伦理解释框架。新的伦理解释框架是递归的科技道德问题与道德设计创造性的变量函数值,亦是当代科技发展中新的人与技术关系方程式。

“China Shock”or China Dividend?-China GVC Participation’s Effects on Trading Partners’Technological Progress

This paper explores the effects of China’s global value chain(GVC)participation on technological progress in trading-partner countries based on estimated data on value-added trade between China and 52 trading partners.We find that,first,although China’s exports lowered the total factor productivity(TFP)of its trading partners(competitive effect),its imports greatly increased trading partners’TFP(effect of scale).This implies that China’s GVC participation is beneficial to its trading partners’technological progress in the form of a considerable technology dividend effect.Second,China’s export dividend effect compensates for the negative effect of Chinese competition on trading partners’technological progress;the innovation effects attributable to China’s imports reinforce the positive effects of scale on technological progress.When innovation is factored in,the China dividend thus becomes further reinforced.Third,China’s merchandise imports have a diminishing positive effect on technological progress in trading partners as geographical distance increases,but trade in services transcends geographical boundaries,and the positive technological progress effect of China’s service imports do not diminish as distance increases.We find that the“China dividend”from China’s GVC participation is a significant contributor to technological progress in partner nations,and China’s imports are conducive to innovation and technological progress in developed countries in the long run.

对外直接投资的逆向技术溢出:基于国内大循环的视角

基于2009—2013年中国上市公司及其供应商是否发生对外直接投资的面板数据,从微观视角分析对外直接投资对国内供应商创新的影响。研究发现:(1)“间接”参与OFDI同样能够获得显著的创新外溢效应,即客户OFDI行为通过国内生产网络显著提高了供应商的创新水平;(2)“间接”参与OFDI通过信息传递效应、规模经济效应、客户重要性提升效应和研发支出效应四种机制发挥作用;(3)从客户-供应商关系来看,当客户与供应商间地理距离较近、关系持续时间较长、客户集中度较低时,“间接”参与OFDI对国内供应商的创新溢出效应较强,从企业和投资目的国特征来看,企业规模较大、国有企业、低中发展水平地区、投资目的国为高收入国家时,“间接”参与OFDI对国内供应商的创新溢出效应较强。本研究对促进国内国际双循环相互联动和企业加快形成新质生产力具有重要的启示意义。
