Manufacturing Localization,Technology Backfire,and Economic De-globalization

Since the global financial crisis,global value chain(GVC)have been contracting amid the trend toward economic de-globalization.With GVC participation rate in mind as the core indicator of economic de-globalization,in this paper we create a multi-country general equilibrium model to characterize the mechanism by which manufacturing localization affects GVC participation rate.Our theoretical derivation shows that changes in the local manufacturing status of final products in various countries directly influence the GVC participation rate of those countries.When the local proportion of a country’s final products reaches a certain level,rising local proportion of intermediate inputs,economic growth below the world average level,and technology progress all cause the country’s GVC participation rate to decline,giving rise to de-globalization at the manufacturing and trade levels.We further provide a comprehensive interpretation based on an empirical test of the deep-seated causes of economic de-globalization in relation to such economic phenomena as increasing trade concentration,the“technology backlash”effect of the new industrial revolution,and economic growth driven by the combined forces of trade protectionism and quantitative easing.

Productivity Growth, Technological Progress, and Efficiency Change in Vietnamese Manufacturing Industries: A Stochastic Frontier Approach

This study applies a stochastic frontier production approach to decompose the sources of total productivity (TFP) growth into technical progress and changes in technical efficiency of 8057 firms in Vietnamese manufacturing industries during 2003-2007. Using both total manufacturing industry and sub-manufacturing industrial regressions, the analysis focuses on the trend of technological progress (TP) and technical efficiency change (TEC), and the role of productivity change in economic growth. According to the estimated results, the annual technical progress for the manufacturing industry and sub-manufacturing industries are calculated directly from the estimated parameters of the translog stochastic frontier production function by taking a partial derivative of output with respect to time t. The average technical changes in manufacturing industry and sub-manufacturing industries are positive, with an average technical change about 5.2%, 5.8%, 5.4%, 11.8%, 4.6%, 4.1%, 7.3%, 4.8%, 4.8% and 4.8% for total sample, food products & beverages, textile & wearing apparel, footwear, paper & products, industrial chemicals, rubber & plastic products, non- metallic mineral, basic & fabricated metal and other sub-industries, respectively. Total TFP in the manufacturing sector has grown at the annual rate of 0.052, although the rate of growth decreased continuously during the sample period. For the sub-industry estimates during the sample period, TFP grew fastest in the footwear sub-industry, with annual average growth rate of 11.8%, followed by the rubber & plastic products with a rate of 7.3%, and the food products & beverages with a rate of 5.8% per annum.

Next 10 years in pharmaceutical manufacturing information technology

Today the ASEAN Pharmaceutical manufacturing companies are still focusing on their local countries,with the exception of a fewlarge regionals who are already and increasingly looking and capable to export to the outside markets such as Europe.This means that the majority of companies producing medicinal products to higher regulatory standards have less international experience/exposure in handling the GMP requirements demanded by PIC/s[1].In addition most of their processes are manual with legacy practices,and mostly the data and controls are in paper with a very high amount of data made with pen and paper on numerous human reviews of documentation mainly to assess the data is complete but not for accuracy of the data at the time that action could be taken—data integrity on paper has been shownto be highly questionable.
