1. Introduction

With the development of information technology, there are many changes on business environment: the trend of economic globalization, the competitions of enterprise, the shorter lifecycle of product, the demand of time and quality etc. Manufacturing system functional objective decision is jointly influenced by customer demand and competition strategy. The traditional manufacturing system functional objectives only pursue the harmony of low cost and high efficiency, which can not adapt to the current trend, such as agile manufacture, Mass Customization, networked manufacture, intelligent manufacture etc. Manufacturing system is the core subsystem of enterprise, which provides satisfactory products to the users for winning market competition. So, functional objective decision is the significant on the design of manufacturing system.

Manufacturing system is an input/output system where manufacturing resources are converted into products or semi-finished products. The system is consisted of manufacturing process and the related hardware, software and personnel. The system involves the whole or part process of product lifecycle, such as market analysis, product design, process plan, manufacturing process, assembly, transport, product sales, after sales service, and recycling process etc. Different from production technology, the research objectives of manufacturing system are not only traditional technological behaviors, but are consisted of economy, society, humanity and other integrated factors as well. Therefore, manufacturing system should be considered as economic, social, humane environment, namely complex social large system. The basic functional objectives of manufacturing system should be research on TQCESE (time, quality, cost, efficiency, service and environment). Manufacturing system functional objectives are mutual restrictions; even, with contradictory, for example, high quality and low cost, high efficiency and satisfactory service. Analyses of relationship among customer demand, competitive strategy and manufacturing system functional objectives, is the key problem of manufacturing system to respond to market demand, to carry out strategic intent of enterprises, to obtain sustainable competitive ability and to resist highly uncertain manufacturing environment. Compared with the previous studies, we establish the relationship on analysis schemes of TQCESE, which can be of more significance to grasping the direction of development. By means of empirical research, this paper validates the relevance of customer demand and competitive environment to functional objectives, which is to provide theoretical basis for manufacturing system of Chinese enterprises to make scientific decisions.

2. Research plan

2.1. Conceptual framework of the research

This paper based on previous research results, related theories and panel discussion establishes conceptual framework of the research, as Figure 1 says. In this figure, customer demand not only directly affects manufacturing system functional objectives, which are also indirectly affected by competitive strategy.

Figure 1. The hypothesis path

2.2. Definition and measure of the variables

To ensure validity and reliability of measuring tool, this paper uses the scales which have been used by the existing literature at home and abroad and are amended on the basis of research objectives as far as possible.

The scales of customer demand mainly come from the research of [1-12], among which there are 13 items including 2 factors which are customer satisfaction and customer loyalty in all. The scales of competitive strategy of supply chain mainly come from the research of [13-32], among which there are 12 items including 3 factors which are operation layer, financial layer and strategic layer. The scales of manufacturing system functional objectives mainly come from the research of [33-43], among which there are 21 items including 6 factors which are cost, quality, service, efficiency, flexibility and environment.

3. Hypothesis testing

3.1. Theoretical basis and research hypothesis

3.1.1. Customer demand

Many scholars define customers from different angles. For example, Levis and Papageorgiou (2005) considers customer demand is the agreement of competitive strategy, benefit sharing and risk sharing between buyers and sellers. Tsai and Chen (2010) believes customer demand is that for the same objective different customers invest related resources which are mainly time and money, to make efforts to reach product objective quality and quantity stetted by themselves. Zäpfel (1998) claims customer demand is a relationship between customer and enterprise which is based on the trust towards each other, the total risk, benefit-sharing awareness, achieving competitive advantage and creating greater performance. Tiemessen, Fleischmann, van Houtum, van Nunen and Pratsini (2013) maintains that it is an agreement between sellers and buyers, by which enterprises could achieve objectives of mutual benefit, the total risk, sharing profit.

In summary, this paper defines customer demand as the one which is formed between consumers and enterprises, benefit-sharing, risk-sharing, long-term, stable and cooperative. Establishing forecasts and management of customer demand can attain the objectives of reducing cost, diversification of risk, gaining critical resources and improving competitive position.

While, what aspects shall we proceed from to measure customer demand? On the basis of the opinions of Babakus, Yavas and Ashill (2009), customer satisfaction and customer loyalty are two factors of measuring customer demand. Customer satisfaction is a product of the performance to meet customer expectations, which is the basis for customers to buy again. Customer loyalty refers to the customer for a product with attachment or affection, the behavior of repeat purchasing the enterprise products as a habit. It is more practical to measure the consumer demand for the product through these two factors.

3.1.2. Competitive strategy

Competitive strategy is considered as the base of realizing enterprise market share (Claver‑Cortés, Pertusa-Ortega & Molina-Azorín, 2012; Acquaah & Yasai-Ardekani, 2008). Most scholars argue that the upstream and downstream of supply chain can alleviate effect by competitive strategy (Information Sharing), to improve supply chain performance (Heijltjes & van Witteloostuijn, 2003). What aspects of information should supply chain partnership share? Salunke, Weerawardena and McColl-Kennedy (2011) point that in supply chain organizational complete competitive strategy should contain: partners are willing to share sales forecasting information and technical information; both sides understand product sales’ degree etc. Deeming competitive strategy of supply chain can be divided into four aspects: order processing information, operation information, strategic information and competitive information.

According to the existing literature, this paper divides competitive strategy content of supply chain into three aspects: operation information, financial information and strategic information. Operation information is mainly about order processing information, stock amount, production scheduling, production capacity planning and Order forecasting etc. Financial information is mainly about sales data sharing, production cost and profit etc. Strategic information mainly provides the information of increasing the rate of reaction and reducing the uncertainty of demand for enterprises.

3.1.3. Manufacturing system functional objectives

Cost, customer service, flexibility, due date and innovations are always applied by manufacturers to evaluate performance or operational objectives. Ahn, Lee, Song and Kim (1998) apply six indexes which are stock, time, order fulfillment, quality, customer focus and customer service to evaluate performance of supply chain. Tegarden, Sheetz and Monarchi (1995) apply four kind of competitive advantages which are cost, quality, due date and flexibility to analyze manufacturer performance. Kalogeraki, Melliar-Smith, Moser and Drougas (2008); Gregoriades and Karakostas (2004) apply cost, quality, flexibility and innovations to discuss automobile manufacturer performance. Based on the above researches, this paper applies four variables which are cost, service level, time and innovations to measure manufacturing system functional objectives. Cost performance applies two items to evaluate: low production cost and the decrease of overall cost; customer service applies three items to evaluate: order satisfaction rate, distribution punctuality and out of stock rate; time applies two items to evaluate: the production lead time shortened and time to market of new products shortened; innovations apply two items to evaluate: new product quality and existing products’ function increasing.

3.2. The relationship among customer demand, competitive strategy and manufacturing system functional objectives

3.2.1 Customer demand and competitive strategy

The closer the relationship between customer and enterprise is, the easier they share information with each other, even more willing to change its internal information system reinvestment to reduce the problem of the drop of informatization level, to improve the capacity of manufacturing system. Agus and Hassan (2011) points, in terms of the action of competitive strategy, when there isn’t customer demand, manufacturing system functional objectives are the key factors for the success of manufacturing system which balance planning skills and executive ability of competitive strategy. When enterprise strategy and manufacturing system are integrated in the interactive process, there will be close contact between each other, which can promote prospective and customer demand satisfied actions. Lockamy III and Smith (1997) says, reliant relationship in organizations will influence the ability of information flow, and the accuracy of determining customer demand will help enterprises to make competitive strategy and resist market risk. Ray and Jewkes (2004) argues, future leaders regard customer value, commercial appeal, individuation and variety as competitive centre whose key influencing factors are individuation and variety of customer demand. Bolloju, Schneider and Sugumaran (2004) considers, customer demand is the basis of competitive strategy, and cultivating responsible relations is propitious for enterprises to timely adjust strategy. Thus, this paper puts forward the first hypothesis.

H1: customer demand has a significant positive impact on the performance of competitive strategy.

3.2.2. The relationship between competitive strategy and manufacturing system functional objectives

Draman, Altinel, Bajgoric, Unal and Birgoren (2001) considers, adding the preference of competitive strategy can reduce Bull Whip Effect of manufacturing system caused by insufficient competitive strategy. Zhang, Zhang, Xu and Li (2011) holds, competitive strategy obviously affects manufacturing system functional objectives, that is, the higher degree of competitive strategy can give an index to higher performance of manufacturing system. Manufacturing system is an important medium for the implementation of competitive strategy, which needs timely adjustment in accordance with competitive strategy. So, this paper puts forward the second hypothesis.

H2: competition strategy has a significant positive effect on manufacturing system functional objectives.

3.2.3. The relationship between customer demand and manufacturing system functional objectives

The customer demand strongly affects the performance of the manufacturing system (Hadden, Tiwari, Roy & Ruta, 2007). When the intensity of customer demand is more and more dependent on manufacturing system functional objectives, manufacturing system will show significant changes by transforming its functions. Because, when relations that customer demand depends on manufacturing system functional objectives change, different functional objectives of the system will be adjusted anew, which in order to response to market opportunities makes the system has the ability to respond to customer demand and makes both sides more efficiently match resource to achieve the same objectives. So building relationship between customer demand and manufacturing system functional objectives will improve the dependent degree between customers and enterprises, and then improve operating performance of manufacturing system. Therefore, this paper puts forward the third hypothesis.

H3: customer demand has a significant positive impact on manufacturing system functional objectives.

3.3. Research sample

This research mainly studies the relationship among customer demand, competitive strategy and manufacturing system functional objectives. Manufacturing industry is the one which has the characteristics of obvious manufacturing system. So manufacturing industry is the research model, and the research objects are basically the enterprises of automobile industry, chemical industry, computer and related equipment industry, appliances industry, mechanical industry, telecommunication industry and textile industry in the manufacturing industry. The field of investigation is the northeast of China.

On the basis of enterprise yellow pages of the northeast of China, this paper randomly chooses the sample enterprises intended to investigate, then gets in touch with the executives by phone. After ensuring they accept investigation, the action begins. Meanwhile EMBA students, senior manager training class and MBA students of Harbin Institute of Technology, Jilin University and Northeastern University are chosen, which gathers a lot of business executives, and ask them to fill out this questionnaire when they are free. All the students come from the northeast of China, which have comparative cultural backgrounds to understand this questionnaire.

1000 copies of questionnaires are sent. 756 copies of questionnaires are taken back, among which there are 14 copies of invalid questionnaires whose answers are not complete and 742 copies of valid questionnaires. Manufacturing industry is the research object, so 54 copies of non-manufacturing enterprises questionnaire are deducted. 688 copies of questionnaires are actually used. The investigation time is from March 1, 2012 to October 30, 2012.

3.4. Factor analysis

Aiming at customer demand and manufacturing system functional objectives, this paper uses factor analysis to extract main factors. In the customer dimension, consists of 15 items (A1~A15, such as Table 1), to measure the customer demand. After retrieving data, factors are analyzed by SPSS16.0. This paper starts with principal components analysis, takes 4 factors whose value is 1 plus, and rotates their shafts by maximum variation. After the first factors analysis, the paper finding interpretation degree of 6 items which are A4, A7, A10, A12, A14, A15 is worse, so they are deleted. Then analyzing the remaining 8 items whose qualities are higher, the results are shown in Table 2. The value of KMO is 0.770, which is greater than Kaiser (1974) that the least value of KMO is 0.5, which shows that there are a lot of common factors in the variables, it is adapted to adopt factor analysis; Bartlett’s test of sphericity（P‑value）:0, which reaches significant level, meaning correlation matrix of the population has common factors, it is adapted to adopt factor analysis, and 2 factors extracted can explain the whole variant 71.086%.

4.2. Path analysis of customer demand, competitive strategy on manufacturing system functional objectives

This paper analyzes the relationship of various factors of three variables among customer demand, competitive strategy on manufacturing system functional objectives above, but doesn’t analyze the interactions between variables. Due to Figure 1, customer demand may not only have a direct impact on the manufacturing system functional objectives, but also indirectly affect the manufacturing system though influencing competitive strategy. So path analysis is needed. In the path analysis, two multiple regression are conducted. Firstly, manufacturing system functional objectives are regarded as the dependent variables; customer demand and competitive strategy are regarded as the independent variables. Secondly, competitive strategy is regarded as the dependent variable; customer demand is regarded as the dependent variable.

The results are shown in Figure 2. There are 3 outstanding paths of manufacturing system functional objectives. The first one is customer demand directly affect manufacturing system functional objectives, the path coefficient is 0.492; the second one is competitive strategy directly affect manufacturing system functional objectives, the path coefficient is 0.294; the third one is customer demand indirectly affect manufacturing system functional objectives though competitive strategy, the indirect effect is 0.136. The overall influence of customer demand on manufacturing system functional objectives is 0.631; competitive strategy’s is 0.294, such as Table 11.

Annotation: the data in the table is the standardized coefficient, the values in parentheses is t coefficient; * means p < 0.1; ** means p < 0.05; *** means p < 0.01).

5. Conclusions

The results further confirm the argument scholars discussing which is customer demand and competitive strategy have significant positive effects on manufacturing system functional objectives. So, satisfying customer demand and lifting the core competence will be beneficial to improve manufacturing system functional objectives.

Moreover, satisfaction degree and loyalty degree of customer demand have important positive effects on operation information, strategic information and financial information of the performance of competitive strategy. And satisfaction degree and loyalty degree of customer demand have momentous positive effects on cost, quality, service, efficiency, flexibility and environment of manufacturing system functional objectives. It says that when conducting competitive strategy, manufacturing enterprises of the northeast of China should pay attention to the bearing capacity of manufacturing system functional objectives. More importantly, the overall influence of customer demand on manufacturing system functional objectives is higher than that of competitive strategy. That is to say, when conducting competitive strategy, manufacturing enterprises of the northeast of China, should pay more attention to satisfy customer demand. Because the influences of customer demand on enterprise operation is comprehensive and far-reaching.
