Abstract
Purpose
The purpose of this paper is to improve the dimensional accuracy of inclined thin-walled parts fabricated by laser direct metal deposition (DMD) under an open-loop control system.
Design/methodology/approach
In this study, a novel method of the adaptive slicing method and DMD process with feedback adjustment of deposition height has been developed to successively fabricate complex inclined thin-walled square tube elbow parts. The defocus amount was used as a variable to the matching between the deposition thickness and the adaptive slicing height.
Findings
The low relative error of dimensional accuracy between experimental and designed parts shows that the matching of the single-layer deposition thickness and the adaptive slicing height can be realized by optimizing the defocusing amount. The negative feedback of the thin-wall part height can be achieved when the defocus amount and the z-axis increment are less than deposition thickness. The improvement of dimensional accuracy of inclined thin-walled parts is also attributed to the optimized scanning strategy.
Practical implications
The slicing method and deposition process can provide technical guidance for other additive manufacturing (AM) systems to fabricate metal thin-walled parts with high dimensional accuracy because the feedback control of deposition height can be realized only by the optimized process.
Originality/value
This study provides a novel adaptive slice method and corresponding the deposition process, and expands the slicing method of AM metal parts.

Abstract
Urban planning is the blueprint for the development of urban construction and the basis for management of a city. The urban planning of China’s high-speed modernization has encountered many bottlenecks, and the gap between the daily living needs of residents and the urban planning objectives has attracted particular attention. Harmonious development between man and nature is necessary to build a harmonious society, and urban planning that is close to the needs of residents and more humanized has become the main goal of urbanization. In this paper, urban planning of Zhuhai City was studied for one year. Zhuhai focuses on building transport hub, industrial layout, and urban development in three major patterns. Many problems in the planning and management of Zhuhai City were encountered in the past, because the plans are only heavy concepts that ignore implementation and lack of comprehensive survey. Based on the concept of communication planning, the main features of the public participation in the urban planning model through modern mass media may be suitable for achieving the objectives and satisfying public needs. Urban planning and decision-making in Zhuhai City in recent years are evaluated by SWOT method. Future plans of Zhuhai City are discussed.

Abstract
Purpose
This paper aims to fill the academic gaps in the study of the new co‐operative movement in China and its innovative mechanisms, and to assess why new co‐operatives deviate from the orthodox co‐operative model represented by the standards of the International Cooperative Alliance (ICA).
Design/methodology/approach
As an alternative to the popular ideal‐co‐operative perspective, the paper employs a historical approach to understand the co‐operative renaissance in China. Afterwards, the paper presents an application as well as an example to reinforce this understanding and to demonstrate the validity of the analysis.
Findings
Using this approach, this paper demonstrates the formation process of real‐type co‐operatives under the influence of institutional legacies as well as resources and environments. Moreover, The shareholding co‐operatives have been developed as new co‐operative forms. They are characterized by their multiple stakeholdership, their multi‐purpose operations, and their orientation to the whole community.
Originality/value
The paper looks for the logic of the dynamics and evolution of the newly emerged co‐operatives, trying to explain their non‐compliance with the ICA standards. It analyses the bottom‐up institutional innovation process and the key role played by co‐operative entrepreneurs. Moreover, it contributes to understanding their hybrid form as a nexus of tensions. Therefore, it helps to explain some of the conceptual and practical difficulties that hamper the understanding of new co‐operative development in China.

Abstract
Purpose
A more accurate comprehension of data elements and the exploration of new laws governing contemporary data in both theoretical and practical domains constitute a significant research topic.
Design/methodology/approach
Based on the perspective of evolutionary economics, this paper re-examines economic history and existing literature to study the following: changes in the “connotation of production factors” in economics caused by the evolution of production factors; the economic paradoxes formed by data in the context of social production processes and business models, which traditional theoretical frameworks fail to solve; the disruptive innovation of classical theory of value by multiple theories of value determination and the conflicts between the data market monopoly as well as the resulting distribution of value and the real economic society. The research indicates that contemporary advancements in data have catalyzed transformative innovation within the field of economics.
Findings
The research indicates that contemporary advancements in data have catalyzed disruptive innovation in the field of economics.
Originality/value
This paper, grounded in academic research, identifies four novel issues arising from contemporary data that cannot be adequately addressed within the confines of the classical economic theoretical framework.

Abstract
Purpose
The paper aims to reveal how the Chinese government has tried to regulate transnational cultural flows by applying cultural policies.
Design/methodology/approach
The paper compares the dissemination of different foreign television programmes in China since the 1980s. The documents of cultural policy released since 1990s, news reports and the statistics of imported dramas since 2000s will be analyzed.
Findings
The research finds that the Chinese government has treated cultural products from different countries in unequal ways. Political-diplomatic relationships and the need for ideological control, influence the making of cultural policy. Restricting the quota of imported dramas, censorship and propaganda are measures taken by the Chinese government to regulate transnational cultural flows.
Research limitations/implications
The paper mainly focuses on platforms such as state-owned television stations and internet. The role of pay-cable channel in disseminating imported dramas should be taken into consideration in the future research.
Practical implications
The paper provides a systematic understanding on the development of Chinese cultural policy.
Originality/value
The paper offers an alternative approach to explore the policy-oriented dissemination of transnational cultural flows other than market-oriented dissemination.

Abstract
Purpose
This paper examines the different features of China's economic development in different stages of economic globalization. The study finds that the investment- and export-based growth model drove China's high-speed economic growth between 2000 and 2007, which came into existence around 2000 when China plugged into the global production network.
Design/methodology/approach
This paper also finds that China slowed down to the New Normal because of the disruption to the socio-economic underpinnings of this growth model. As China adapts to and steers the New Normal, supply-side structural reforms can channel excess capacity to the construction of underground pipe networks in rural areas of central China and fix capital while advance rural revitalization.
Findings
At the same time, enterprises must strive to build a key component development platform for key component innovation and the standard-setting power in global manufacturing.
Originality/value
The establishment of a domestic production network integrating the integrated innovation-driven core enterprises and modular producers at different levels can satisfy the dynamic demand structure of China in which standardized demands and personalized demands coexist.

The purpose of this paper is to propose an integrative approach for improving failure modes and effects analysis (FMEA).
Abstract
Purpose
The purpose of this paper is to propose an integrative approach for improving failure modes and effects analysis (FMEA).
Design/methodology/approach
An extensive literature review on FMEA has been performed. Then, an integrative approach has been proposed based on literature review. The proposed approach is an integration of FMEA and quality function deployment (QFD). The proposed approach includes a two-phase QFD. In the first phase, failure modes are prioritized based on failure effects and in the second phase, failure causes are prioritized based on failure modes. The proposed approach has been examined in a case example at the blast furnace operation of a steel-manufacturing company.
Findings
Results of the case example indicated that stove shell crack in hot blast blower, pump failure in cooling water supply pump and bleeder valves failed to operate are the first three important failure modes. In addition, fire and explosion are the most important failure effects. Also, improper maintenance, over pressure and excess temperature are the most important failure causes. Findings also indicated that the proposed approach with the consideration of interrelationships among failure effects, failure mode and failure causes can influence and adjust risk priority number (RPN) in FMEA.
Research limitations/implications
As manufacturing departments are mostly dealing with failure effects and modes of machinery and maintenance departments are mostly dealing with causes of failures, the proposed model can support better coordination and integration between the two departments. Such support seems to be more important in firms with continuous production lines wherein line interruption influences response to customers more seriously. A wide range of future study opportunities indicates the attractiveness and contribution of the subject to the knowledge of FMEA.
Originality/value
Although the literature indicates that in most of studies the outcomes of QFD were entered into FMEA and in some studies the RPN of FMEA was entered into QFD as importance rating, the proposed approach is a true type of the so-called “integration of FMEA and QFD” because the three main elements of FMEA formed the structure of QFD. In other words, the proposed approach can be considered as an innovation in the FMEA structure, not as a data provider prior to it or a data receiver after it.

Abstract
Purpose
The purpose of this paper is to investigate the economic significance of informal borrowing between friends and relatives in rural China. Guided by an economic model of household‐production interactions, the paper provides results from a survey of over 1,500 households including general linear model and logistic regression results. The paper finds evidence of a “small farm bias” in the use of informal credit, but the paper cannot generalize this to credit rationing as a matter of course. In part, it is believed that a preference for informal borrowing is related to some forms of credit rationing, spillover effects and collateral as some literature suggests, but the results suggest that by no means are these mutually exclusive or exhaustive.
Design/methodology/approach
This paper uses regression techniques based on 1,557 farm household surveys gathered by the authors in Shaanxi, Gansu and Henan Provinces in 2007 and 2008.
Findings
The paper argues that informal lending amongst friends and relatives cannot be dismissed as a significant economic factor in the financing of China's agricultural sector. A small farm bias in formal lending is indicated by the results, but there are many factors other than credit rationing which affect a households' decision to borrow informally.
Research limitations/implications
The research is limited to the survey data used. China's agricultural economy is too large to assert that the informal‐formal relationships described herein are general, even though the results are supported by other research.
Practical implications
The paper makes the case that the study of agricultural finance in China should include informal lending as part of any credit study. In addition, the paper argues that the use of the term “informal lending” should not generally group familial lending with other forms of interest‐bearing loans such as pawn shops or money lenders.
Social implications
China's rural credit needs are huge and many farmers do not have access to formal credit. This paper argues that the strength of trust relationships between friends and family is sufficiently high that nearly 60 percent of all credit outstanding is between friends and relatives at zero interest rates.
Originality/value
This, it is believed, is one of the first comprehensive studies on informal lending in China.

Abstract
Purpose
The purpose of this paper is to provide an overview of the farm and rural credit system in China. To do this the authors use the so‐called “7 Cs” of credit (these include: Credit, Character, Capacity, Capital, Condition, Capability, and Collateral) and for each “C” provide some aspect of importance related to agricultural finance.
Design/methodology/approach
This paper is largely based on a survey of 897 farm households in Shaanxi and Gansu provinces, and extensive interviews of agricultural lenders conducted in the summer and fall of 2009. These data are used in simple form and in regression form to explain a variety of credit issues in China.
Findings
A number of key factors related to credit delivery and demand are found. First, using the 7 Cs as a guide proved to be very fruitful for disentangling the many institutional and cultural facets affecting rural credit in China. Under “Character” the authors discuss the cultural characteristics of the Chinese farmer in terms of informal lending and borrowing; under “Capacity” the authors discuss the challenges of delivering credit to farms with limited resources; under “Condition” the authors discuss group guarantees and credit worthy villages, credit rationing and insurance and incomplete markets; under “Capability” the authors discuss income inequality and challenges in economies of scale and size; and for “Collateral” the authors discuss the implications of lack of collateral and limitations on farm economic growth due to the collectivization of land and the potential for agricultural lending from the transferability and mortgagability of land or forestry use rights.
Research limitations/implications
Although the assessment provides a great deal of breadth and depth across many credit‐related issues in China, it is not an exhaustive study. Agricultural and rural credit in China is very complex and in many instance under developed. The survey results from Shaanxi and Gansu tell a story that is consistently told throughout China, but the authors would caution against using the data to characterize farm credit across China as a whole.
Social implications
Large swaths of China have either no or very rudimentary credit services. Even in areas where credit is in supply there are issues of poverty that could be aided with credit access and delivery. In order to improve livelihoods through credit institutions, it is important to understand rural credit in many dimensions. This paper takes a step in that direction.
Originality/value
Despite the importance of rural credit in China, it is largely understudied and not well understood. This paper makes progress in providing such an understanding. Our reasoning for using our unique approach is that by understanding the 7 Cs of credit one comes to understand the elemental characteristics of the credit decision from the lender's point of view but in a way that takes into account conditions at the farm level. The 7 Cs provide an objective approach to credit assessment that balances both the supply of and demand for credit.
