This study examines the impact of e-commerce on the survival rate of small and medium enterprises(SMEs)during the COVID-19 pandemic using a combined dataset from the Enterprise Survey for Innovation and Entrepreneurship in China for the period from 2018 to 2020.We conducted a difference-in-differences analysis by exploiting the variation in the adoption of e-commerce across SMEs before and after the outbreak of COVID-19.The results show that e-commerce had a significantly positive effect on the survival rate of SMEs during the crisis.Specifically,it improved the survival rate of SMEs by 3.0 to 3.4 percentage points by expanding the scale of the enterprises'markets,mitigating declines in orders,shortening the repayment periods of accounts receivable,and improving cash flow during a pandemic.Heterogeneity analysis reveals that the impact of e-commerce was more pronounced for SMEs with a larger share of online sales and for labor-intensive SMEs,and third-party e-commerce platforms or Web sites played a bigger role than self-built Web sites and social media.This study offers novel evidence highlighting the value of digitalization for firms during the crisis. 展开更多

Innovation development has received increasingly more attention from academia and policymakers. The policy-making for promoting it heavily relies on evidence provided by measuring national innovation development. This study tries to build a bridge between innovation development measurement and policy-making. The literature shows that there is very limited theoretical and methodological research on measuring national innovation development. This paper proposes a national innovation development index(NIDI) for measuring the performance of national innovation development by integrating the definition of innovation from five perspectives and the definition of development from four perspectives. The NIDI consists of five sub-indexes, science and technology development sub-index, innovation condition development sub-index, industrial innovation development sub-index, social innovation development sub-index, and green & low-carbon development sub-index, which is measured by the composite sub-index approach. This paper uses the NIDI methodology to investigate 40 countries based on the panel data from 2006 to 2015, which helps classify countries into three categories including leading, advanced and catching-up countries. The cross-analysis between sub-indexes of the NIDI brings new insights into the competitive advantage and disadvantage, which helps governments to choose more specific policies to overcome shortcomings resulted in the poor performance of sub-indexes of the NIDI so as to improve their innovation development performance systematically. Besides, the findings in this article indicate that the level of economic development in a country is to a large extent determined by the level of national innovation development. 展开更多

This paper clearly defines the concepts of the national competitiveness,the national S&T competitiveness,and the national S&T competitiveness structure.It develops an evaluation framework with three dimensions:the national S&T competitive potential,the national S&T competitive strength and the national S&T competitive effectiveness.This paper proposes a structure analysis method and depicts the national S&T competitiveness structure of 35 countries in an empirical research.Apart from the definitions and the structure analysis method,this paper mainly draws the following conclusions:(1)In the one-dimensional national S&T competitiveness structure,the top 5 countries were all developed countries in 2015,while the developing countries generally performed better than developed countries considering the average annual growth rate of the national S&T competitiveness index.The 35 countries are clustered into 4 categories using the two-dimensional structure analysis method.For example,based on the ranking of the national S&T competitive strength index and the national S&T competitive effectiveness index of the 35 countries in 2015,the 35 countries are clustered into four categories:high-strength and higheffectiveness,low-strength and high-effectiveness,low-strength and low-effectiveness,and high-strength and low-effectiveness.(2)To a large extent,there is a significant correlation between the national S&T competitiveness index score and the GDP per capita value.And to a certain extent,there is some correlation between the national S&T competitiveness index score and the GDP value.Moreover,under the background of strength and effectiveness combination,or under the background of strength and potential combination,the national S&T competitiveness structure and GDP or GDP per capita show significant relationship. 展开更多

The national innovation capacity(NIC) has received increasingly more attention from academia and policy makers. This study develops a methodology for measuring NIC with a view to provide the evidence for policy-making concerning national innovation capacity-building, and conducts a crosscountry comparison based on the panel data of 2006-2015.(1) National innovation capacity index(NICI) is established to measure the performance of NIC from two perspectives, namely national innovation strength index(NISI) and national innovation effectiveness index(NIEI).(2) Developed countries usually perform better than developing countries in terms of the NICI if there is no huge gap in economic scale between two kinds of countries.(3) Emerging countries show greater imbalance between the NISI and the NIEI, and have generally higher average annual growth rate of the NISI and the NIEI than that of developed countries.(4) National innovation strength is closely related to national economic scale while national innovation effectiveness is closely related to national development level. Some theoretical considerations in this research may make contributions to innovation development studies.(1) NIC is regarded as the capacity for scientific discovery and technology invention, and for driving economic, social and environmental development, which emphasizes the driving effect and the influence of innovation on development.(2) The concepts such as the NISI and the NIEI are introduced to measure the NIC so as to distinguish the contribution of the size of innovation activities to the NIC and the contribution of the efficiency and efficacy of innovation-driven development to the NIC.(3) The indicator system of the NICI is designed from the perspective of the full spectrum of capacity-building process ranging from input to output by introducing the "innovation condition" as a broad sense "innovation input" and the "innovation outcome" as a broad sense "innovation output". 展开更多
