Motivated by the problems that the positioning error of strap-down inertial navigation system (SINS) accumulates over time and few sensors are available for midwater navigation, this paper aims to propose a self-aided SINS scheme for the spiral-diving human-occupied vehicle (HOV) based on the characteristics of maneuvering pattern and SINS error propagation.

First, the navigation equations of SINS are simultaneously executed twice with the same inertial measurement unit (IMU) data as input to obtain two sets of SINS. Then, to deal with the horizontal velocity provided by one SINS, a delay-correction high-pass filter without phase shift and amplitude attenuation is designed. Finally, the horizontal velocity after processing is used to integrate with other SINS.

Simulation results indicate that the horizontal positioning error of the proposed scheme is less than 0.1 m when an HOV executes spiral diving to 7,000 meters under the sea and it is inherently able to estimate significant sensors biases.

The proposed scheme can provide a precise navigation solution without error growth for spiral-diving HOV on the condition that only IMU is required as a navigation sensor.

This study investigates the effect of renting in land on farm productivity, and the impacts of rented-in land size and transaction partner type on farm productivity.

Data from the 2015 China Household Finance Survey are analyzed using an extended regression model and the two-stage least squares method.

Farm households that rent in land are likely to achieve higher farm productivity, and ignoring endogeneity underestimates the positive effect of land renting-in. Further evidence indicates that rented-in land size has an insignificant impact on farm productivity, and that there is no difference in farm productivity between lessees renting-in land from acquaintances and those renting-in land from non-acquaintances. These results may be caused by the higher degree of marketization of land rentals between acquaintances in China. With increasing competition in agricultural factor markets, in theory, rented-in land size should not affect farm productivity.

Overall, the analysis suggests that renting in land improves farm productivity, which supports the land transfer policies that have been rolled out in recent decades in China. However, our finding that rented land size does not affect farm productivity, consistent with the results in the literature, implies that the Chinese government should no longer subsidize or prefer large farms with low productivity. More attention should be paid to small lessees and market-oriented land rentals between acquaintances. Promoting the marketization of land transfers inside acquaintance networks could realize the potential of the land market, especially if land transfers decrease.

This study identifies the effects of renting in land, rented-in land size and type of rental transaction partner on farm productivity using nationally representative data. The findings imply that the government should pay more attention to the marketization of land rentals between acquaintances. Although existing studies regard land rental between acquaintances as informal and of low efficiency, the recent evidence shows that China's land markets are changing, and policy makers should adjust their policies accordingly.

The purpose of this paper is to assess the links between basic farmland preservation and land transfers in rural China.

The Chinese provincial panel data from 2006 to 2016 were analyzed with the use of Arellano–Bond linear dynamic panel data estimations.

The basic farmland preservation policy negatively affects the land transfer rate. In addition, this policy is most likely to limit land transfers between local acquaintances in the major grain-producing areas. Further evidence indicates that the basic farmland preservation policy has a negative impact on land rentals in general. Considering that land transfers such as exchanges and take-overs are excluded from rental transactions between acquaintances, the policy’s constraints on land use are likely to hinder land rentals between acquaintances, which are market-oriented.

Overall, this study’s analysis suggests that the farmland preservation policy’s constraints on land use rights are likely to result in a major diminishment of the rural rental markets. Under this policy, land that is designated as basic farmland cannot be converted to another use. However, it remains possible to improve the productivity of agriculture through other means. These possible avenues for improvement include enhancing the efficiency of production through expanding the scale of farming operations and developing the social services aspect of agriculture (i.e. the basic farmland preservation policy is likely to realize more social revenue than can be gained from land transfers). Thus, the arrangement of the basic farmland preservation policy in China can be managed in a way that is both economical and reasonable.

To ensure food security, China has enacted several laws and regulations to preserve basic farmland, and it has promoted land transfers to improve farm productivity. Therefore, it is important to understand whether the basic farmland preservation policy restricts land use rights and hinders land transfers that could improve productivity. This study provides empirical evidence showing that the basic farmland preservation policy is actually not conducive to promoting land transfers and that it even discourages the market orientation of land rentals between acquaintances. In dealing with this issue, the Chinese Government should seek to balance the relationship between preserving basic farmland and promoting land transfers.

The purpose of this paper is to analyse the key elements in the strategy of leading Chinese private firms in order to identify the key factors that are associated with the success of these firms.

Secondary data source from the self report of 30 of the top 50 private enterprises of 2004 in China as the basis for analysis. In analysing these self reports, a table was compiled that records the name of each case study firm, nature of its businesses, its ranking in the top 50 in 2004, background of the owner entrepreneur/CEO, history of the firm, and key elements of strategies.

The paper identifies that the key success factors of these firms appear to be associated with firm growth through business diversification, development of international market, strong emphasis on product innovation and quality enhancement, strategic marketing, product and corporate branding, and importantly, entrepreneurship of owner managers/CEOs and reform of corporate governance. Also revealed that top‐performing Chinese private firms tend to adopt a high‐commitment model of human resource management which emphasizes training and development, promotion by competence, extensive employee welfare provision, and enterprise culture development and management.

The secondary data came from company self reports with potential bias of self reporting. They were snap shots and anecdotal instead of longitudinal studies. They also contained top management's views only, which are not necessarily representative of the wider organisation. These methodological drawbacks mean that the data needs to be treated with caution and that more in‐depth empirical research is needed to shed more light on the subject that is of growing importance in understanding Chinese business and management.

This paper fills the gap in existing literature by revealing changes that have taken place in the privately owned businesses in China, key challenges they face and what strategic response they have adopted. The understanding of the business and management strategies of these firms is beneficial not only to scholars and students who are interested in China but also to organisational managers who wish to develop businesses with China.

Shareholder heterogeneity reflects the interactive relationship between shareholder groups of different industries and ownership types. This paper aims to discuss the impact of shareholder heterogeneity on ambidextrous corporate innovation.

Combining questionnaire and database data, this study empirically analyzes the internal mechanisms of the impact of shareholder heterogeneity on ambidextrous corporate innovation.

The authors find that shareholder heterogeneity can promote ambidextrous corporate innovation and that board’s decision-making processes play an intermediary role. Specifically, shareholder industry-type heterogeneity promotes ambidextrous corporate innovation by improving procedural rationality in board’s decision-making process, and shareholder ownership-type heterogeneity promotes ambidextrous corporate innovation by improving political behavior in board’s decision-making process. The analysis of the impact degree shows that shareholder industry-type heterogeneity has a greater impact on exploitation innovation, while shareholder ownership-type heterogeneity has a greater impact on exploratory innovation. In addition, the research also shows that shareholder groups dominated by industry-type heterogeneity have an impact on corporate innovation by shaping an engaged board with higher procedural rationality and lower political behavior. Shareholder groups dominated by ownership-type heterogeneity have an impact on corporate innovation by shaping a contested board with higher political behavior and lower procedural rationality.

This study not only enriches the research on shareholder heterogeneity and corporate innovation in the context of transformation but also provides an analytical framework for research on board’s decision-making process.

The purpose of this paper is to review the development of the processed feed industry in China through the lens of one of its most successful and earliest entrants, the Hope Group's “New Hope” enterprise. With the feed industry in China now facing a transition phase, the paper looks at the root causes of the problems facing China's feed industry, analyzes the transition strategy undertaken by New Hope and others, and discusses the opportunities for industry growth in the world's most populous country, where urbanization and standards of living are still on the rise and per capita use of feeds is still low by world standards (e.g. one‐fifth of that in the USA). The case also addresses the potential industry impact of mandates outlined in China's Twelfth Five‐Year Plan, such as the imperative to modernize agriculture and improve peasants’ economic well‐being.

The paper draws on expert knowledge of the CEO of New Hope Group's sister agribusiness company, West Hope Group, as well as New Hope Group annual reports and global economic data.

The study reveals future challenges to China's processed feed industry as being price of labor, raw materials, and energy rises; companies undergoing integration; and established companies shifting from product marketing to service marketing models.

This paper is useful for academics interested in industry perspectives, policymakers, practitioners, and business people considering investment in China.

How China's processed feed and breeding industries modernize will impact the economic well‐being of each link in the nation's agribusiness chain (from small producers to conglomerates), the cost and quality of animal‐based proteins, and the world's “food vs. fuel” conflicts.

The paper offers a rare insider's look at one of China's largest private companies and a global player in agribusiness.

Low levels of human capital in rural China are rooted in the poor schooling outcomes of elementary school students. The purpose of this paper is to provide insight into the distribution of academic performance in rural China and identify vulnerable groups.

The authors draw on a data set of 25,892 observations constructed from 11 school-level surveys spanning nine provinces and one municipality in China conducted from 2013 to 2015.

The authors find that the distribution of academic performance is uneven across provinces and subgroups. In general, male students, Han, living in richer counties, living with their parents and studying in rural public schools do better academically than female students, non-Han, living in poorer counties, left behind and studying in private migrant schools in cities.

Using the results of this study, policymakers should be able to better target investments into rural education focusing on at risk subpopulations.

With limited data sources, the research on the academic performance of students in rural China is largely absent. The findings of this study help to fill the gaps in the literature base.
