The Dispersion of Productivity Change and Efficient Allocation of Capital in an Industry – A Case Study of China's Manufacturing Industry
Yongjun Chen Yongfeng Liu Zida Lin
Abstract: The efficient of resource allocation is not only decided by whether the market is perfect or not, but also impacted by a firm’s productive process. This paper built a dynamic model of firm’s capital input to clarify its productive process, proved the effect of the dispersion of firms’ productivity fluctuations on the efficiency of capital allocation by using four linear regression equations, and pointed out the reason of this effect is the existence of capital adjustment cost. Also, one moment equation shows that the dispersion of firms’ productivity fluctuations is related to the uncertainty which firms were meeting in their productive process. Then, by using the data of industrial firms in China from 1999 to 2007, this paper confirmed the relation between the dispersion of firm’s productivity fluctuations and the efficiency of capital allocation empirically, and estimated the function of capital adjustment cost by using simulated moments method, then this paper calculated the goodness of fit which is 0.96 to certify that the theoretical model which includes capital adjustment cost is effective. The research results of this paper provide a new way to improve the efficiency of capital allocation, that is, to create a relatively stable industrial environment and to reduce the capital adjustment cost.

Research on the Optimal Industrial Organization and Inspiration of Anti-monopoly Regulation: Based on Firm Number and Firm Size and Industrial Output
Abstract: From the general combination of industrial market demand curves and firm cost curves, and based on the scientific definition of average firm’s market demand curves in an industry having different concentration degree, a graphic measure model on the optimal industrial organization is built according to the efficiency goal of maximum economic profit, and three key indexes of industrial organization including optimal firm number, firm size and industrial output are defined. Research shows that the optimal industrial organization is the objective existence, which mainly conditioned by the industrial market demand and firm technical cost. The optimal industrial organization is different with the different industries, and monopoly would be the best under special circumstances. Anti-monopoly regulation should take different practice according to the different industries, and set a unified standard for all industries is not suitable.

The Influence of Taxi Market Structure aroused by The Fringe Entry of Online Car-hailing Service——Taking Beijing as an Example
Chang Meng Chiming Qi
Abstract：The taxi market is under dual control of quantity and price in most urban of China. The government establishes administrative barriers to entry to control the quantity, these policies create monopoly rent and rent-seeking interest groups. Based on the investigation and official data, this paper analyzes the present control problems of taxi market in Beijing. Then establish theoretical model based on the fringe entry theory to explore the influence of the taxi market structure aroused by online car-hailing service. The main conclusion is that the fringe entry of online car-hailing reduces the welfare of regulators and the benefits of traditional taxi group, and high monopoly “rents” won’t be maintained with the fringe entry of online car-hailing service. The analysis of the investigation on current situation of taxi operation shows that strict control of online car-hailing service will lead to the deadweight loss of social welfare. The government should proceed from the social public interest, gradually lift the administrative barriers to entry into the taxi market, and establish operational vehicle service quality standard registration system to replace the administrative control over the quantity, change economic regulation into social regulation.

Is it Necessary for Chinese “Bricks-and-mortar” Retailers to Carry out Online Sales Business?
Xiangdong Liu Chengzhang Chen
Abstract: Using listed retail firm level data in China, this paper uses GMM estimation of a dynamic panel data model to analyze the effects of the adoption of online channel on the sales of “bricks-and-mortar” retailers in China under the framework of difference in difference. It finds that after controlling for labor input and capital input, and the time effect, there is no significant improvement in the firm’s sales after it started to provide online shopping service. Besides, after dividing the whole sample into supermarket format sample and department store sample, the result are basically consistent. Such conclusion remains the same based on the two-step method for robustness test. According to these results, this paper tries to give an appropriate explanation from the comparative analysis of the differences in the structure of the retail industry between China and the United States. Based on the findings of this paper, the “bricks-and-mortar” retailers can’t only regard the Internet as a new selling channel, but make full use of the Internet technology to improve themselves.

Chenyue Qi Zemin Hou
Abstract: Industrial efficiency measurement and industrial evolution are the important contents in industrial organization theory. This paper takes Nanjing tourism industry as an example, selecting the input and output data from 2003 to 2014, on the basis of considering the negative input of the ecological environment, toanalyze the tourism efficiency of Nanjing and to reveal the efficiency characteristics and change models of Nanjing tourism industry. The result shows that: (1) The comprehensive efficiency of Nanjing is growing, and comprehensive efficiency has a high correlation with the scale efficiency, which dominates in comprehensive efficiency of Nanjing.Technology efficiency presents a stable situation, however, it had a decline in 2011 and 2013. (2) The tourism industrial model of Nanjing is changing over time. In the previous years, scale efficiency plays an important role in Nanjing’s tourism efficiency and increasing returns to scale is a key mode, while in today, technology efficiency is dominant and tourism efficiency become decreasing returns to scale. (3) Nanjing should give much attention to technologyrather than scale input in improving tourism efficiency.
