Recent technological advances and trade liberalization have made India a major player in international cotton markets. In the year 2011-2012, India was the world＇s second largest producer, consumer and exporter of cotton. The increasing role of the Indian cotton sector in international markets is a direct challenge to other major players like the US. Within this context, a better understanding of the Indian cotton sector and the impact of mechanization on cotton cultivation are needed. The overall objective of this paper is to assess the competitiveness of Indian cotton producers and potential implications for India as a competitor in the world cotton market if it mechanizes harvesting of cotton. The results demonstrate that the net income of the Indian cotton farmers will increase considerably with the mechanization of cotton harvesting. But the adoption of the practice of harvesting cotton by mechanical means is possible only if efforts from many private and public agencies come together. In that scenario, the cotton production in India can increase considerably which can impact the international markets.展开更多

What is the impact of competition on incentives to invest, and on capacities to invest？ What is the role of the rate of penetration and technical progress？ This paper highlights the fact that investment incentives are positively related to potential for technical progress. Investment incentives also depend on market structure, competition intensity, and penetration rate, but not monotonically. This paper consists of a theoretical part which, under assumptions of full market coverage and market share symmetry, shows that for each national market, there is a target level of investment which companies strive to achieve but had not exceeded, and an empirical part that confirms the findings of the theoretical part and explains the differences with the theoretical part by relaxing the assumptions of full coverage and market share symmetry. This target level on the one hand depends on the potential for technical progress and on the other hand, depends on the rate of penetration. From a social perspective, this target level is the best amount that companies are encouraged to invest. Non-achievement of the target level entails underinvestment and a decrease in consumer surplus and welfare and may slow down technical progress. A data set covering 30 countries over a period of eight years is used to empirically prove the existence of a change in investment behavior depending on whether or not the target level is achieved. A low margin per user may hamper achievement of the target level. As a result, maximum consumer surplus and welfare occur under imperfect competition but not under perfect competition.展开更多

The acceptable walking access area is determined according to the willingness of passengers to walk who prefer rail transit compared with bus and automobile. Empirical studies were conducted using the survey data of six stations from the rail transit in Nanjing, China. The results indicate that the rail transit is more preferable compared with bus and private automobile in this case when excluding the influence of individual and environmental factors. It is found that passengers tend to underestimate their willingness to walk. The acceptable walking access area of every rail transit station is different from each other. Suburban stations generally have a larger walking access area than downtown stations. In addition, a better walking environment and a scarcer surrounding traffic environment can also lead to a larger walking area. The model was confirmed to be effective and reasonable according to the model validation. This study can be of benefit to the passenger transportation demand estimation in the location planning and evaluation of rail transit stations.展开更多

The study found that Hunan automobile industry cluster competitiveness is relatively weak, full of the very big promotion space; further research shows that the human capital investment, fixed capital investment, land investment and policy support are the main factors influencing the efficiency of automobile industry cluster in Hunan province.展开更多
