中印双边贸易的互补性及比较优势

运用显性比较优势指数、贸易强度指数、贸易互补性指数,对中国和印度两国的商品贸易结构进行比较。实证分析表明,中印之间存在着贸易互补性,但不同行业有很大差异;中印之间不存在非常显著的贸易联系,两国贸易存在较大的空间。     

Technological convergence and trade patterns

Textbook trade theory would suggest that emerging and developing countries specialize in lower-tech industries. In this paper the authors take a dynamic view on development and trade integration and distinguish three types of catching-up processes (the continuous-convergence approach, the climbing-up-the-ladder approach and the jumping-up approach). Using data for 25 countries and 32 industries the authors empirically analyze the different patterns of catching up over the period from 1981 to 1997. Further, they discuss linkages between technological convergence, dynamics of comparative advantage and trade patterns. JEL no. F14, L6, O10, O14, O30, O41.     

大数据背景下智慧城市空间规划与建设方法

随着信息化、大数据以及数字孪生技术的快速发展,建设智慧城市已经成为国家城乡一体化与协同发展的重要课题,传统的城市空间规划方法已经不适应现代高速发展的城市建设,因此城市转型既是必然要求也是时代所需。通过对数字孪生、智慧城市等文献的梳理,认为在大数据的背景下可以为城市规划提供相应的城市空间规划研究方法,应运而生了一种新的数据思维理念和城市规划方法,并从多个角度分析和解决新形势下的城市问题。因此,以智慧城市规划方法研究为主线,从智慧城市空间规划背景概述、智慧城市规划方法与建设重点以及智慧城市未来可持续发展策略3个框架,对传统城市的框架进行丰富和补充,对新型城镇化建设以及数字城市的发展具有重要意义。     

Trade in Parts and Components and the Industrial Geography of Central and Eastern European Countries

Growing inflows of FDI and the increasing integration of domestic firms into International Production Networks (IPNs) set up by EU-15 partners have yielded a rise in trade in parts and components for Central and Eastern European Countries (CEECs). As a consequence, new patterns of localization of industrial activities have been observed in the region since the mid-1990s. In this paper, I propose a comprehensive model of trade and production which tries to explain cross-country variations of sectoral output by comparative advantages (Ricardo, Heckscher–Ohlin) and agglomeration forces (home market effect, market potential), with a focus on the role played by trade in middle products. The empirical implementation reveals that the higher is the involvement in IPNs the larger is the domestic share of regional output. Comparative advantages are a crucial determinant of localization as opposed to agglomeration forces. I argue that these results can be interpreted as an assessment of the predictive power of two alternative trade theories. JEL no.  F10, F12, F14, F15     

The Danish Agro Machinery Industry in a Global Perspective, 1945–2005

Abstract

Since the mid-nineteenth century, agriculture and the agro machinery industry has formed an integral part of the developed world, dominated by North America and Western Europe. After the Second World War, agricultural industrialization speeded up. Millions of small and mixed farms in the West disappeared to be replaced by large-scale and specialized farming. The technology needed to transform agriculture was supplied by an expanding agro machinery industry. As in other fields of industry, the agro machinery industry turned into an international business. By the turn of the twentieth century, farming and industry took an even bigger step as business and technology were being globalized. The agro machinery industry that served these global markets remained in the West, however. Eventually, transatlantic mergers consolidated firms into industries for plant, dairy and pig and poultry farming equipment. This article discusses how the Danish agro machinery increasingly became an integrated part of international and global developments.

集成电路产业上市公司高创新效率多元路径研究

以2019-2021年我国上交所科创板集成电路产业38家上市公司为研究对象,基于TOE(技术-组织-环境)理论框架构建集成电路产业上市公司高创新效率6个前因变量.通过DEA(数据包络分析)测算得出的企业创新综合技术效率作为结果变量,从而运用fsQCA(模糊集定性比较分析法)进行企业高创新效率组态考察.研究结果表明,单一影响因素不能构成企业高创新效率影响路径,需要由两个或两个以上影响因素共同作用,形成外部资金驱动型、技术+外部资金驱动型、人才+外部资金驱动型、内外资金驱动型以及全面要素驱动型5条高创新效率影响路径.研究结果对集成电路产业相关企业提高创新效率具有一定参考意义.     

Toward regional financial and monetary cooperation in East Asia1

The financial and economic crisis in 1997–98 came as a dramatic shock to East Asian economies, and has prompted to institutionalize a regional financial and monetary cooperation. This paper demonstrates the strong will of East Asian countries to develop the regional financial and monetary cooperation, outlines recent developments, and provides possible prospects for the future. It points out that the option to keep consistent with the IMF system actually weakens regional solidarity, and recommends an immediate establishment of a strong regional surveillance and peer pressure mechanism for the Chiang Mai Initiative (CMI) to evolve into a common pool of foreign exchange reserves, a sort of East Asian IMF. It also argues that East Asian countries should closely coordinate their exchange rate regime to maintain intra‐regional and extra‐regional exchange rate stability.
