A Study of Human Papillomavirus Genotypes Specificity and the Vaccines Introducing System for Korean-Chinese Women in the Yanbian Autonomous Region.

Objectives:Human papillomavirus (HPV) is a major cause of cervical cancer in women. The characteristics of HPV infection vary; therefore, it is necessary to identify the most common HPV genotypes among a group of subjects when introducing a vaccine program. Currently, in the Yanbian Autonomous Region, no HPV vaccinations are not provided, and no data has been reported regarding HPV rates or genotype prevalence. We aimed to find the most suitable HPV vaccine for this region and reasons why no vaccine has been introduced. Methods:HPV genotyping of 200 Korean-Chinese women living in the Yanbian Autonomous Region who visited the hospital for annual health examination was done. We also checked main factors necessary for HPV vaccine administrative system; (1) vaccine manufacturers in China, (2) vaccine importers, (3) vaccine suppliers, (4) applicable vaccine laws, (5) the HPV vaccine permit system in Jilin Province, and (6) vaccination hospital facilities-were assessed by direct inquiry and search. Results:The results showed that HPV genotypes 52, 58, 16, 53, and 33 were the most common among Korean-Chinese women. These results differed from those previously reported for Korean or Chinese women. All elements necessary for introduction of HPV vaccine were prepared, but there is no HPV vaccination plan based on epidemiological investigation. Conclusions:Gardasil® 9 should be the most suitable vaccine for Korean-Chinese women with HPV infection and cervical cancer in this region considering the prevalence of certain genotypes. Governments and medical institutions should take an active stance on HPV vaccination to lower the incidence of cervical cancer here. Our study may serve as an important reference for introducing a Chinese government program designed to prevent cervical cancer.

Ecological Assessment of Clay Brick Manufacturing in China Using Emergy Analysis

Clay brick is a commonly used building material in China. Due to the enormous land destruction and excessive consumption of resources, such as materials and energy in the manufacture of clay brick, it is important to study its overall sustainability, i.e., in terms of impact on the environment, services, and economy. In this study, emergy analysis is employed, which offers a holistic perspective, unlike typical environmental studies. A series of emergy indices such as renewability rate (R%), nonrenewability rate (N%), unit emergy values (UEVs), emergy yield ratio (EYR), environmental loading ratio (ELR), and emergy sustainability index (ESI) were used to study manufacturing of clay brick. In addition to calculating UEVs of clay brick manufacturing in China (7.18 × 1012 sej/kg), our detailed analysis shows that the nonrenewable resources and imported energy have a dominant impact on the emergy contribution (50.6%) and within the nonrenewable resources, clay is the foremost item, accounting for 33.5% of local emergy inputs. Given different electricity UEVs, the change ranges of clay brick system UEVs are 14.9% (scenario 1), 7.24% (scenario 2), 8.91% (scenario 3), and 6.94% (scenario 4). Furthermore, several policy suggestions are discussed for improving the sustainability of the evaluated system, involving the energy structure adjustment, recycling material replacement, and promotion of energy-saving systems.

The impact of information technology usage on supply chain resilience and performance: An ambidexterous view

Scholars and practitioners have recognized the importance of supply chain (SC) resilience. However, it remains unclear how to build SC resilience and whether SC resilience can enhance firm performance and bring values to customers. By analyzing data collected from 206 manufacturers in China, this study empirically examines how firms implement different information technology (IT) patterns (exploitative versus explorative) with SC partners to achieve supplier and customer resilience from information processing theory, and examines the performance implications of these two dimensions of SC resilience. In addition, this study also investigates how IT ambidexterity reconciles the paradox between IT exploitation and IT exploration in enhancing SC resilience. The results show that both supplier and customer resilience could improve SC performance. To achieve the two aspects of SC resilience, only explorative use of IT with suppliers and customers have significant effects. The results also show that the ambidextrous use of IT on the customer side takes effect. The exploitative and explorative use of IT complement each other to improve customer resilience. The findings of this study contribute to IT and SC resilience literature.

Globalization and the labor share in China: Firm‐level evidence

AbstractThis study examines the relationship between economic globalization (measured by exports and foreign direct investment) and the labor share in China's manufacturing sector. Using a large firm‐level panel dataset for 2001–2007, we find that the labor shares are significantly higher in exporting firms and foreign‐invested enterprises (FIEs), where the export status is more important than foreign ownership. The origins of the FDI and export types do matter. The aforementioned positive associations are primarily driven by ordinary exports and FIEs from Hong Kong, Macau, and Taiwan, whereas processing exports exhibit a negative association with the labor share. Our baseline results are about the between‐firm variations within industries. When controlling for firm fixed effects, the labor share remains to be higher for a firm becoming an exporter or increasing export intensity, while the labor share is lower when a firm get a foreign investor or increase their exports. Finally, total factor productivity and innovation are negatively correlated with the labor share, suggesting that technological progress may play a role in the decline of the labor share in China.

The Impact of Information Technology Investment on the Performance of Apparel Manufacturing Enterprises: Based on the Moderating Effect of Equity Concentration

As a relatively large production and trade industry in China's manufacturing sector, apparel manufacturing has entered the data analytics era with much-enhanced productivity by using information technology. The extent to which the state-of-the-art information technologies can increase the productivity of this entire industry has not been fully investigated. This article selects 30 Chinese listed apparel manufacturing enterprises from 2012 to 2018 as a sample and analyzes the impact of information technology investment on their performance using the panel fixed effect and random effect models. In addition, the moderating effect of enterprise equity concentration on the abovementioned relationship is studied. Equity concentration reflects the distribution of equity from the total amount. Excessive equity concentration enables large shareholders to obtain higher control rights with smaller cash flows, seizing the interests of small and medium shareholders and digging tunnels. This is, thus, not conducive to healthy and long-term development of the firm. The results show that information technology, such as software investment, hardware investment, and total information technology investment, can improve the enterprise performance. Among them, software investment has the greatest impact on the enterprise performance. When the proportion of the software investment increases by 1%, the enterprise performance increases by 17.6%. The equity concentration has a negative impact on the relationship between the investment in information technology and enterprise performance.

Effects of Urban Producer Service Industry Agglomeration on Export Technological Complexity of Manufacturing in China.

Based on the measurement of producer service industry agglomeration and export technological complexity of manufactured products in 288 Chinese cities from 2000 to 2015, this paper illustrates the evolvement and spatial characteristics of the two factors through visualization figures, and discusses the effects of producer services agglomeration on export technological complexity of manufacturing through robust panel data models. The findings are as follows: as with the influence of industrial connection, empirical outcomes indicate that urban producer service agglomeration can promote technological complexity of export manufacturing on the full-sample level. Visualization analysis shows that the scale of producer service industry agglomeration and the export technological complexity of manufactured products around Chinese cities kept rising constantly during the study period. However, although the export technological complexity displayed a trickle-down effect, the producer service industry agglomeration experienced continuous polarization both on the national and the regional levels. Accordingly, as is shown in the empirical analysis by areas, regions with strong support from producer service industry saw a remarkable promotion in the export manufacturing technology, while the northwest and the northeast gradually lagged behind. Such results sufficiently prove that heterogeneity does exist in the performances of industrial connection between producer service industry and export manufacturing in cities of different regions in China.

A loosely-coupled deep reinforcement learning approach for order acceptance decision of mass-individualized printed circuit board manufacturing in industry 4.0

Printed Circuit Board (PCB) manufacturing is a kind of energy-intensive and pollution-intensive industries. With the increment of individualized requirements, PCB manufacturers face massive customized orders with a variety of specifications. The individualized customization on orders results in large differentials of the profit, energy consumption, and environmental pollution. Making energy-efficient order acceptance decisions can reduce carbon consumption and improve material utilization during the whole manufacturing process. An order acceptance decision model is established based on a loosely-coupled integration of deep learning and reinforcement learning techniques. Firstly, different from a simple assumption of the linear cost function in a small-scale manufacturing system, the deep learning algorithm is presented for accurately predicting the production cost, makespan, and carbon consumption of incoming PCB orders in the large-scale manufacturing system. Secondly, these predicted cleaner production indicators are combined with original order features to perform a reinforcement learning-based order acceptance decision. The proposed loosely-coupled deep reinforcement learning approach is verified with a dataset built based on data collected from a PCB manufacturer in China. This research is expected to provide an environment-friendly order acceptance decision-making approach for sustainable manufacturing in the Industry 4.0 context.

Fast saccharide mapping method for quality consistency evaluation of commercial xylooligosaccharides collected in China

Due to the extensive use of xylooligosaccharides (XOS) as functional food ingredients, many inferior goods and even adulterants are generally found in the market, which may pose a health hazard to certain populations. Chromatography method such as high-performance liquid chromatography (HPLC) and high-performance thin-layer chromatography (HPTLC) is traditionally applied for the quality analysis of XOS. However, it is time consuming due to the prolonged separation and pre- or post- derivatization procedure. In this study, a fast saccharide mapping method based on matrix-assisted laser desorption/time-of-flight mass spectrometry (MALDI-TOF-MS) was developed for the quality consistency analysis of 22 batches of XOS collected from different manufacturers in China. The time needed for saccharides analysis using MALDI-MS was less than 30 min for one plate, at least 6 times faster than that by the traditional HPTLC chromatography method. In addition, MALDI-MS possessed higher resolution for XOS with DP4-DP7 based on the difference of m/z, which is hardly separated using HPTLC. The results showed that XOS were present only in samples XY01-XY11, samples XY12-XY14 only consisted of hex oligosaccharides, and samples XY15-XY22 were free of oligosaccharides. These indicate that the quality consistency of XOS products in the China market was poor, which should be carefully investigated.

The interrelationship between intellectual capital and firm performance: evidence from China's manufacturing sector

PurposeThe purpose of this paper is to examine the impact of intellectual capital (IC) and its components (human, structural and relational capitals) on the performance of manufacturing listed companies in China. This paper also investigates the impacts of company ownership, industry attributes and region on the IC-performance relationship.Design/methodology/approachThe study uses the data of 953 manufacturing companies listed on the Shanghai and Shenzhen Stock Exchanges over the period 2012–2016. The modified value-added intellectual coefficient (MVAIC) model is applied to measure IC efficiency. Finally, multiple regression analysis is employed to test the research hypotheses.FindingsThis study reveals that IC can enhance firm performance in China's manufacturing sector. Overall, earnings are affected by physical capital, human capital (HC) and structural capital (SC), and profitability and productivity are influenced by physical capital, HC, SC and relational capital. Physical capital is the most influential contributor to firm performance. In addition, state-owned enterprises have a greater impact of IC on firm performance than private-owned enterprises; high-tech manufacturing companies have higher IC performance than non-high-tech manufacturing companies; manufacturing companies in China's eastern region have higher IC performance than the counterparts in central and western regions.Practical implicationsThe findings may help managers, stakeholders and policymakers in developing countries to effectively and efficiently manage their IC resources.Originality/valueThis is the first study to evaluate IC and its relationship with firm performance among Chinese manufacturing listed companies using the MVAIC model.

Kekuatan Pasar (Market Power) dan Pangsa Ekspor Produk Ban (HS4011) Indonesia dan Negara Pesaing di Malaysia dan Filipina

The exporters of Indonesian and Thailand tire products have the same capability in price mark-ups in the Malaysian market. The price mark-up capability of tire exporters from Indonesia, Thailand and China is greater than the domestic tire industry in the Philippines. However, China has a greater share of tire exports in the Malaysian and Philippine markets and is likely related to China's ability to be able to increase the export composition of various types of tires. Indonesia needs to encourage the domestic tire industry to increase the production capacity of various types of tires through investment and relocation of the tire industry to Indonesia amid the downward trend in China's manufacturing industry. Need to develop tire products for the types of trucks, buses, tractors and heavy equipment that are often used in the construction, agriculture, mining and cargo transportation ports to enlarge market share in Malaysia and the Philippines because Indonesia has competitiveness from the aspect of raw materials. The potential export of various types of tires in the two export destination countries is a challenge to increase the number of exports of Indonesian tire products.

Analysis of Molecular Heterogeneity in Therapeutic IFNα2b from Different Manufacturers by LC/Q-TOF.

Recombinant human IFNα2b (rhIFNα2b), as an important immune-related protein, has been widely used in clinic for decades. It is also at the forefront of the recent emergence of biosimilar medicines, with numerous products now available worldwide. Although with the same amino acid sequence, recombinant proteins are generally heterogeneous due to post-translational modification and chemical reactions during expression, purification, and long-term storage, which could have significant impact on the final product quality. So therapeutic rhIFNα2b must be closely monitored to ensure consistency, safety, and efficacy. In this study, we compared seven rhIFNα2b preparations from six manufacturers in China and one in America, as well as four batches of rhIFNα2b preparations from the same manufacturer, measuring IFNα2b variants and site-specific modifications using a developed LC/Q-TOF approach. Three main forms of N-terminus, cysteine, methionine, and acetylated cysteine were detected in five rhIFNα2b preparations produced in E. coli (1E~5E) and one in Pseudomonas (6P), but only the native form with N-terminal cysteine was found in rhIFNα2b preparation produced in Saccharomyces cerevisiae (7Y). Two samples with the lowest purity (4E and 6P), showed the highest level of acetylation at N-terminal cysteine and oxidation at methionine. The level of oxidation and deamidation varied not only between samples from different manufacturers but also between different batches of the same manufacturer. Although variable between samples from different manufacturers, the constitution of N-terminus and disulfide bonds was relatively stable between different batches, which may be a potential indicator for batch consistency. These findings provide a valid reference for the stability evaluation of the production process and final products.

The Influence of Manufacturing Export Trade on Marine Ecological Environment in China

Li, Y.L., 2020. The influence of manufacturing export trade on marine ecological environment in China. In: Bai, X. and Zhou, H. (eds.), Advances in Water Resources, Environmental Protection, and Sustainable Development. Journal of Coastal Research, Special Issue No. 115, pp. 631-635. Coconut Creek (Florida), ISSN 0749-0208.With global warming, extreme climate and other environmental issues becoming increasingly prominent, the impact of import and export trade on Marine ecological environment has attracted more and more attention. Based on the current situation of China's manufacturing export, this paper discusses the deficiencies of China's current trade environment and its impact on the Marine ecological environment from the perspectives of policy norms, export structure, technology and concepts. The results show that China is at the low end of the global value chain, the role of processing and manufacturing makes China bear more pollution while becoming a manufacturing power, and taking labor-intensive and resource-intensive industries as China's comparative advantages to participate in the international division of labor will have a negative impact on China's Marine ecological environment. The low-end structure of exports, mainly manufactured goods, has further polluted China's Marine environment.

Based on this, this paper first introduces the theoretical basis of the transformation and upgrading of the marine manufacturing industry, then studies the measurement and evaluation of the comprehensive effect of the transformation and upgrading of the marine manufacturing industry, and finally gives the promotion strategy of the comprehensive effect of the transformation and upgrading of the marine manufacturing industry.

Improving the production efficiency of sweet potato starch using a newly designed sedimentation tank during starch sedimentation process

Starch sedimentation process in sweet potato starch production traditionally uses sedimentation pond (SP), but it is often time-consuming with contamination issues. In order to improve the production efficiency, a sedimentation tank (ST) was designed, and its effect on the starch and protein contents, bacterial composition, and pH of the slurry was evaluated in comparison with the SP. The sedimentation process using ST took 12 hr less time, and it resulted in more thorough starch sedimentation with 0.76% less starch content in the surface liquid. The higher initial pH of ST (6.01–6.69) contributed to less protein contamination of starch. The bacteria composition later in the starch sedimentation process was significantly different in two production equipment, with Leuconostoc and Lactobacillus being the dominant bacteria in ST and SP, respectively. All these results confirmed that ST was more efficient for starch sedimentation with less production time, increased starch yield, and improved starch quality. Practical applications This study was conducted during real production operation in one of the largest sweet potato starch manufacture in China. The results demonstrated that the utilization of ST had apparent advantages over SP in industrial-scale production. Moreover, similar sedimentation equipment and procedure can also be applied to the production of other starch products, such as potato starch, corn starch, and wheat starch.

The environmental effect of trade liberalization: Evidence from China's manufacturing firms

AbstractWhile prior literature on trade liberalisation and the environment has mostly focused on the macroeconomic ramifications, this study explores at the firm level whether and how changes of trade barriers brought about by China's accession to the WTO may impact on its manufacturing firms’ environmental performance. Adopting a difference‐in‐differences (DID) methodology, we document the effects of tariff reductions on improving firm‐level SO2 emission intensity, and the key corporate strategic decisions responsible for delivering the observed results, with robustness tests covering other major pollutants. In response to trade liberalisation, firms are found to increase labour resources for environmental protection and to improve their production processes to reduce emission intensity. This study contributes to the literature by investigating at the level of the operating firm how output and input tariff reductions may impact on environmental performance and uncovering for the first time the specific actions responsible for the results.

The threshold effect of firm size on technological innovation: examination of panel data from China

PurposeThe purpose of this paper is to explore the threshold effect of firm size on technological innovation using panel data from 2007 to 2012 for listed enterprises in China's manufacturing sector.Design/methodology/approachConsidering the aim of research question is to examine the nonlinear relationship, this paper utilizes the threshold regression proposed by Hansen's (2000).FindingsBased on a threshold regression model using panel data from 2007 to 2012 for listed enterprises in China's manufacturing sector, we find a series of new results. This nonlinear relationship is under the restrictions and impacts of various factors, such as industry characteristics and government subsidies. The results suggest that the threshold regression model well explains the complicated nonlinear relationship and transition process, and it can also shed light on management practice and policy.Originality/valueThere are categorical arguments regarding why firm size is not as effective as before in explaining the monotonic principle of industrial innovation, especially for establishing an effective industrial policy in a particular situation. One of the important reasons is that we have begun to adopt a new perspective from the nonlinear view on the relationship between firm size and industrial innovation. In this study, we have examined the threshold effect of firm size on industrial technological innovation, which is the most representative nonlinear relationship.

Value Co-Creation Behavior in Green Supply Chains: An Empirical Study

As an important supply chain development strategy, green investment and sustainability are concerns of the government and enterprises. However, due to the high cost and low profit of green investment, a large number of small and medium-sized firms can be deterred from their implementation. Value co-creation has become a key measure to solve this problem. This article explores the relationship between the green supply chain (GSC) strategy, value co-creation, and corporate performance in the manufacturing environment, and considers the regulatory effects of internal environmental factors and external environmental pressures on this relationship. Based on data from 115 manufacturers in China, we tested the hypotheses, explained the statistical results, and identified key concerns for implementing GSC through value co-creation. The findings reveal that the GSC strategy can promote a high level of firms’ value co-creation with their supply chain partners, and different value co-creation modes have different effects on firm performance (i.e., operational performance, innovation performance, and financial performance). In addition, the findings indicate that macro-level external pressure and micro-level internal support could enhance such effects. This study enriches the literature with value co-creation modes and GSC management by integrating GSC strategies and value co-creation strategies, providing confidence to the firms and their supply chain partners in value co-creation, thus helping them to better implement a GSC strategy.

Impact of open innovation on organizational performance in different conflict management styles: based on resource dependence theory

PurposeFirms often encounter complicated external relationships and conflicts in inbound and outbound open innovation (OI). Conflict management significantly affects innovation results. Guided by resource dependence theory (RDT), this study aims to examine the moderating effects of conflict management styles in the relationship between OI and organizational performance (OP).Design/methodology/approachThis study focuses on manufacturing and service firms in China, with the respondents composed of senior managers. Using hierarchical regression analysis, data from 270 firm samples are used to empirically test the hypotheses.FindingsInbound and outbound OI openness positively affects OP. Cooperative conflict management positively moderates the relationship between inbound OI openness and OP, whereas it negatively moderates the impact of outbound OI openness on OP. By contrast, competitive conflict management positively moderates the relationship between outbound OI openness on OP.Research limitations/implicationsGuided by RDT, this study explores the relationship between OI and OP and the moderating role of conflict management styles. However, it does not measure the level of resource dependence, which is among the future research directions for further validating the results of this study.Originality/valueThis study is among the first to investigate the impact of OI on OP in different conflict management styles. Findings suggest that choosing a suitable conflict management style may strengthen the positive effects of OI on OP.

Research on the Characteristics of Industrial Agglomeration in Manufacturing and Producer Services

The spatial agglomeration of industries not only promotes the development of the economy, but also accelerates the innovation of the industry. It is of great significance for rationalizing the economic layout, optimizing resource allocation, establishing a spatial innovation system, and forming regional competitive advantages. At present, China's manufacturing and productive service industries are showing different industries and regional agglomeration trends, the manufacturing industry agglomeration is more obvious, the agglomeration of producer services has the characteristics of non-equilibrium and urbanization agglomeration economic, gradually move towards collaborative gathering.
