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.

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.

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.

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.

FDI and Technology Spillover in China

Foreign-invested enterprises＇ influence on China＇s enterprises＇ technology is one of the most important issues. We use the panel data of China＇s state-owned enterprises to analyze this influence. The result shows that the foreign-invested enterprises have a significant influence on the native enterprises. We find that the extent of the technology spillover is positively related to the technological level of the foreign-invested enterprises, while their caoital and asset scales have rather comnlicated influences.

FDI and the technological spillover effects: a comparative analysis on the Yangtze River Delta and the Pearl River Delta

This article calculates the technological spillover effects of foreign direct investment (FDI) in the Yangtze River Delta and the Pearl River Delta through Panel Data, and analyzes the influence on the technological spillover effects of the following factors in these two different areas: human capital, the opening up, R&D and the source of FDI. It makes the conclusion that FDI in different areas has different technological spillover effects and the local governments should make different policies accordingly so as to gain more obvious technology spillover effects.

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.

FDI＇s Spillover Effects on China＇s Growth Quality

Using panel data of 29 regions in China from 1999 to 2007, this paper presents a systematic evaluation of how FDI＇s spillover effects impact the quality of China＇s indigenous econotnic growth, Research outcomes suggest that technology transfers and diffusion have a positive effect on indigenous growth quality. Spitlover effects （mainly competition effect） have primarily negatively affected indigenous growth quality. The effect on indigenous growth quality is positive only in sub-samples with high foreign capital concentration and ,,hen the spillover effect is similar to the technology transfer and diffusion effect brought about by localization. It is also found that technology gaps, foreign capital concentration and value added ratio gaps are important factors affecting the impact of technology transfer and diffusion on indigenous economic growth.

“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.

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.

Technological innovation,market proximity,and China's industrial green development

Due to environmental damage and natural resource scarcity,the promotion of industrial green development to spur the industrial economy is of concern to many countries.We construct a theoretical framework of technological innovation,market proximity,and industrial green development and subsequently test it empirically.First,the results reveal that technological innovation is beneficial to industrial green development;technological innovation has a positive impact on industrial green development in adjacent regions through technology spillover,but human capital spillover has the opposite effect;the international market can effectively promote industrial green development,but the domestic market does the opposite.Second,the interaction between technology spillover,human capital spillover,and domestic and international markets is beneficial to industrial green development.However,the interaction between domestic and international markets imposes an inhibitive effect on industrial green development.Based on the findings,we make recommendations to improve the level of industrial green development.

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.

Technology Spillovers in the Multinational Outsourcing System and Technological Innovation in Recipient Countries

Unlike technology spillovers from FDI or international trade, which operate through a single channel, technology spillovers from multinational outsourcing operate through the combined effect of multiple channels including import spillovers, export spillovers and pure knowledge spillovers. On the basis of the knowledge production function approach, this paper constructs an international R＆D spillover regression equation to test the effect of different technology spillover channels on technological innovation in China＇s manufacturing industry. Research shows that import spillovers are the only channel to have a significant effect, and this varies from industry to industry. Its significance is low in high- tech industry and medium-high in mid-tech and low-tech industries. Empirical findings indicate that China＇s local enterprises are unlikely to achieve technological innovation via ＂learning from importing＂ or ＂learning from communication.＂
