Crop Rotation and Diversification in China: Enhancing Sustainable Agriculture and Resilience

Crop rotation and diversification (CRD) are crucial strategies in sustainable agriculture, offering multiple benefits to both farmers and the environment. By alternating crops or introducing diverse plant species, CRD practices improve soil fertility, reduce pest populations, and enhance nutrient availability. For example, legume-based rotations increase soil nitrogen levels through biological nitrogen fixation, reducing the need for synthetic fertilizers. Moreover, these practices promote more efficient water and nutrient use, reducing the reliance on synthetic fertilizers and minimizing the risk of pests and diseases. This review synthesizes findings from recent research on the role of CRD in enhancing sustainable agriculture and resilience, highlighting the potential contributions of these practices towards climate change mitigation and adaptation. Specific crop rotation systems, such as the cereal–legume rotation in temperate regions and the intercropping of maize with beans in tropical environments, are reviewed to provide a comprehensive understanding of their applicability in different agroecological contexts. The review also addresses the challenges related to implementing CRD practices, such as market demand and knowledge transfer, and suggests potential solutions to encourage broader adoption. Lastly, the potential environmental benefits, including carbon sequestration and reduced greenhouse gas emissions, are discussed, highlighting the role of CRD in building resilient agricultural systems. Collectively, this review paper emphasizes the importance of CRD methods as sustainable agricultural practices and provides key insights for researchers and farmers to effectively integrate these practices into farming systems.

External linkages and regional diversification in China: The role of foreign multinational enterprises

This article investigates the role of local external linkages in supporting regional industry entry in new activities, by specifically considering the role of foreign multinational enterprises (MNEs). Theoretically, we construct an original conceptual framework encompassing different potential trajectories of regional diversification based on the presence of MNEs. Empirically, we focus on the case of 279 Chinese prefectures over 1998–2007 and our results suggest that the presence of MNEs is associated with industry entry in unrelated and complex industries, supporting the idea that regional external linkages can activate processes of diversification that modify the technological and industrial portfolio of local economies.

Export opportunities for Turkey in China under the Belt and Road Initiative: application of a decision support model approach

Turkey's foreign trade deficit with China has rapidly increased since the 2000s. To reduce the foreign trade deficit with China, Turkey needs to identify and diversify potential commodities to export to China with higher competitiveness. In this aspect, this study identifies potential export opportunities for Turkey in China among the Belt and Road Initiative China-Central Asia-West Asia economic corridor countries to increase Turkey's total export volume and diversification in China. The decision support model with some crucial modifications in accordance with regional practices is implemented to pick the export commodities with the highest export potential value. The results of the modified decision support model indicate that Turkey can have export potential, mostly in textiles, metals, machinery/electrical, and miscellaneous. The export promotion strategies for increasing export diversification and volume in China are recommended for Turkey’s future export strategy.

The role of tourism development in boosting export product diversification in China: A provincial perspective

Tourism has emerged as a major sector, and it is considered a significant contributor to the development of the host countries. Tourism development (TD) is believed, inter alia, to be a key promoter of export product diversification (EPD). This study explores the liaison between tourism development and export product diversification in China and across its regions (i.e., Eastern, Central, & Western) using the data for the period of 2011-2019. The Driscoll-Kraay standard errors (DKSEs) is adopted for empirical analysis along with feasible generalized least-squares (FGLS) and panel-corrected standard errors (PCSEs). The findings revealed an inverted U-shaped liaison between the TD and EPD. The estimates are robust and insensitive to econometric models, measures of tourism development, and the inclusion of other key covariates. The relationship between industrial structure, natural resource endowments, human capital, and economic growth is positive and statistically significant. The study revealed similar findings that were significant across regions. The policy insinuation is that the government should devise such policies to boost TD in order to promote EPD and sustainable development.

Fagus diversification in China in relation to East Asian monsoon evolution

When and how the extraordinary species diversity in subtropical East Asia formed is intensely debated, and the available evidence is often inconsistent. In this study, we evaluate the effects of pre- and post- Quaternary events on the evolutionary and biogeographic history of Chinese beech (Fagus species that now occur in China) to gain new insights into the historical establishment and future fate of the East Asian subtropical forest (EASF). A series of approaches and datasets were used to reconstruct biogeographic and evolutionary history of the Chinese beech. They include phylogeography based on the polymorphisms of the complete chloroplast genomes, species distribution models, and a large palaeobiogeographic dataset including 59 pre-Quaternary fossil records, 296 Quaternary fossil records and 3515 modern pollen records. Our multidisciplinary approach suggests that (i) Chinese beech has dispersed to subtropical East Asia and diversified in the early Miocene when the Asian monsoon (AM) intensified; (ii) the last post-glacial warming resulted in limited poleward displacement but significant contraction at southern and lower elevations; (iii) the poleward dispersal of Chinese beech was limited by drought in the early growing season in temperate China, controlled by the East Asian summer monsoon. Our results support the hypothesis that the establishment of the EASF is closely related to the evolution of the AM. More importantly, we suggest that with continued climate warming (e.g., during the last post-glacial period or under current climate change), the monsoon probably hindered rather than promoted the persistence of deciduous beech species, resulting in a decline in species richness.

The Implementation and Refinement of Range Breakout Strategy in Chinese Commodity Market

The range breakout strategy is a momentum strategy that involves taking a long position in a security when its price exceeds a predetermined range and a short position when the price falls below the range. Previous research has indicated that this strategy is well-suited to the price volatility patterns observed in commodity markets. Considering the significant expansion and di-versification of China's commodity market in recent years, we decided to apply the range breakout strategy to China's commodity futures market and assess its feasibility and profitability. Our research utilized historical performance data from the Zhengzhou Commodity Exchange and Shanghai Future Exchange between September 1, 2012, and July 31, 2022, obtained from CSMR as our database. We focused on the top 27 most liquid commodity futures categories to construct our back-testing portfolio. Our approach centered around using volatility as the basis for entry signals in the range breakout strategy and signal weighting as a portfolio construction method. The results demonstrate that the range breakout strategy, based on volatility, is highly effective in China's commodity futures market. This research con-tributes to the enrichment of optimization strategies in China's Future Market. Furthermore, we explored the use of cross-commodity hedging and the Average True Range (ATR) indicator to further enhance the strategy. Although no practical improvements were discovered beyond the original strategy, this exploration offers valuable insights for future research.

Spatial impact mechanism of Chinese technology diffusion on CO2 emissions in the countries along the Belt and Road Initiative.

International climate and green technology cooperation under the Belt and Road Initiative (B&R) have attracted significant attention, which led to several studies exploring B&R carbon emissions from the perspective of driving factors. While existing studies fail to consider the diversification of China's technology spillovers, the stochastic impacts by the STIRPAT and GWTR models are integrated in this study to determine the spatial impacts of three types of international technology spillovers (i.e., foreign direct investment (FDI), imports, and migrants) on the carbon emissions of B&R countries through independent innovations and technology following during 2003-2018. China's FDI and migration technology spillovers will increase B&R countries' CO2 emissions through independent R&D and technology following, while imported technology spillovers will decrease B&R countries' carbon emissions through the same means. Therefore, this study shows that China's three technology spillovers show spatial differences in the CO2 emissions of B&R countries. In short, government departments should formulate low-carbon technology policies according to the technology impact path and regional characteristics.

Integrating agricultural diversification in China’s major policies

Agricultural diversification is proposed as a solution to achieve food security and sustainability in intensified agriculture, but a large-scale policy implementation is lacking. As a leading agricultural producer, the integration of diversification in major policies in China could provide an important example of how to facilitate a sustainable food system transformation globally.

How Does the Sustainable Investment Climate Affect Firm Geographic Diversification in China? Managerial Discretion as a Mediator

Although existing research has explored the main effects of the sustainable investment climate, including political and legal environments, on the performance of firms' geographic diversification, most studies neglect the role of strategic leadership, especially the CEO. The concept of managerial discretion provides a theoretical lens to fill this void. Using a large database from the Investment Climate Survey conducted by The World Bank, which covers 12400 firms from 120 cities among China’s 30 provinces, we empirically prove that the investment climate, including governmental, legal, and financial environments, significantly influence the degree of CEO managerial discretion. Moreover, CEO managerial discretion is positively associated with firm geographic diversification and mediates the relationship between the investment climate and firm geographic diversification. Specifically, the greater the CEO managerial discretion, the lower degree of firm investment within the city and the province in which it is headquartered and the higher level of the firm’s internationalization. Implications for firms’ geographic diversification and constructing a sustainable investment climate for emerging markets are finally given.

The impact of One Belt and One Road Initiative on the diversification of export products from countries along the Belt and Road to China

With the further deepening of the international division of labor and the further extension of the global value chain, the diversification of export products from countries around the world has been further enhanced. "The impact of the initiative on the diversification of China's export products has important practical significance. Firstly, this paper introduces the Herfindal-Hirschman index (HHI) to measure the diversification of export products, and analyzes the current situation of the diversification of export products from countries along the Belt and Road to China based on the data from 2010 to 2019; Secondly, this paper matched CEPII data, United Nations data, World Bank WDI data and the data of the "Belt and Road" cooperation agreement signed with China to form the sample data of 63 countries from 2009 to 2019. Based on the pseudo-natural experiment framework, the dual difference model is used to test the relationship between the participation of countries along the Belt and Road Initiative and the diversification of their exports to China. The research perspective is focused on participating countries and non-participating countries, and a comparative analysis is conducted to explore whether joining the Belt and Road Initiative is conducive to improving the diversification level of export products from countries along the Belt and Road initiative to China compared with countries not participating in the Belt and Road Initiative; Finally, based on the qualitative analysis and empirical analysis above, this paper puts forward a series of countermeasures and suggestions, such as focusing on exporting domestic competitive products, reforming the exchange rate management system and promoting the development of cross-border e-commerce.

Exports diversification as a key point of Сhina’s trade strategy

Nowadays, economic diversification remains a key challenge for most developing countries. The world trading system is developing from universal liberalization to increased protectionism which imposes additional difficulties in countries’ exports development and puts export diversification at the heart of a strategy for economic diversification. China's foreign trade is also in a critical period of rapid development and transformation at present. China is building a new pattern of integration into the world economic system, but its economic transformation is not smooth and faces problems. Taking into account China’s high reliance on exports, one of the most important threat to China’s economic development – the susceptibility to fluctuations in global economy – is largely due to a low level of Chinese exports diversification. In order to achieve a more sustainable long-term economic growth and hedge against the impact of external shocks China needs to diversify its exports markets, range of exported products and trade methods. Purpose. The purpose of the article is the research of practical aspects of exports diversification in China, identification of features and problems of China’s exports product and market diversification, diversification of trade methods and high-tech products exports diversification. Methodology. The methodological basis of the study is presented by the theories of foreign trade and industrial policy, as well as by the researches realized in the field of exports diversification. The information basis of the study are the databases of UNCTAD, WTO and National Bureau of Statistics of China. General scientific methods, systematic approach, economic-statistical methods are used in the research. Findings. An analysis of China’s exports diversification was realized in the article, including revealing of features and problems of China’s exports product and market diversification, diversification of trade methods and high-tech products exports diversification, as well as identification of some driving effects of China’s exports diversification on its economic development and substantiation of the significance to improve its export diversification strategy in order to reduce economic risks and promote the sustainable development of foreign trade.

Molecular phylogeny of moss‐inhabiting flea beetles from the Chabria group (Coleoptera: Chrysomelidae: Alticini) reveals multiple colonizations and radiations in Taiwan

AbstractMoss‐inhabiting flea beetles form a very diverse and understudied ecological group of leaf beetles (Coleoptera: Chrysomelidae) characterized by cryptic lifestyle, loss of flight ability and feeding on mosses as both adults and larvae. We present the first DNA‐based study of the phylogenetic position of moss‐inhabiting flea beetle genera Ivalia Jacoby and Cangshanaltica Konstantinov et al., based on sequences of two mitochondrial and three nuclear genes. We confirm that both genera are members of the monophyletic Chabria group, along with Chabria Jacoby, Parathrylea Duvivier, Chabriosoma Chen and Sutrea Baly. Moss‐inhabiting species form at least three independent lineages within the Chabria group, indicating multiple parallel origin of the association with mosses within the clade. We reveal the monophyly of Cangshanaltica and confirm its separate generic status from Ivalia. Ivalia is revealed as polyphyletic, consisting of at least two unrelated moss‐inhabiting lineages. In contrast, the externally similar moss‐ and leaf‐litter inhabiting genera Mniophila Stephens, Adamastoraltica Biondi et al. and Clavicornaltica Scherer are not closely related to the Chabria group. Our study specifically focused on the moss‐inhabiting flea beetles of Taiwan. We reveal that the Taiwanese fauna is a result of four independent colonizations of the island: one from China (Cangshanaltica) and three from the Philippines (three lineages morphologically assigned to Ivalia). Two of these lineages (Cangshanaltica and the core Ivalia) radiated in Taiwan and gave rise to the majority of modern Taiwanese species. The evolutionary history of Cangshanaltica and its diversification in China are also discussed.

Patterns of Agricultural Diversification in China and Its Policy Implications for Agricultural Modernization.

Based on the value of agricultural farm products produced by different subsectors in China, the foregoing analysis reveals the dynamic character of agricultural diversification by which, this study seeks to examine the evolutionary process of Chinese agriculture through a quantitative study of agricultural diversification at both national and provincial levels. In the initial stages of reform and opening up, the degree of agricultural diversification in the southwest was relatively high; then the center of agricultural diversification gradually moved to the southeast of China; finally, the degree of agricultural diversification in the economically developed eastern provinces was obviously higher than those in other regions in 2019. It was seen that some provinces in the eastern and central south regions moved toward increasing diversification in one direction, and other provinces changed direction, first moving toward diversification and later toward concentration or vice versa. These oscillations implied that there was a cyclic tendency of agricultural diversification along with an increase in per capita GDP. Generally speaking, the patterns of diversification differed across regions due to diversified agricultural subsectors resulting from different natural and socio-economic circumstances. In particular, in less developed regions with lower agricultural diversification levels, farming agriculture persistently dominated the leading position with relatively more resistance to modernizing trends in other aspects of agriculture. It is urgent for the Chinese government to figure out ways off reconciling agricultural productivity with environmental quality through the ecological intensification of agriculture.

Spillovers across industries and regions in China’s regional economic diversification

ABSTRACT Industrial diversification depends on spillovers from related industries and nearby regions, yet their interaction remains largely unclear. We study economic diversification in China during the period 1990–2015 and present supportive evidence on both spillover channels. We add to the literature by showing that these two channels behave as substitutes when explaining new entries and exits, and by using acceleration campaigns of high-speed rail to address some endogeneity concerns with regional spillovers. Our findings confirm the role of relatedness and geographical distance in the diffusion of economic capabilities and support the idea that improvements in transportation can facilitate the diffusion of productive capabilities.

DESIGNING DIVERSIFIED CROPPING SYSTEMS IN CHINA: THEORY, APPROACHES AND IMPLEMENTATION

<List><ListItem><ItemContent> •Agricultural green transformation of China requires restructuring of cropping systems. </ItemContent></ListItem><ListItem><ItemContent> •Ecosystem services enhanced by crop diversification is key to sustainable agriculture. </ItemContent></ListItem><ListItem><ItemContent> •Crop diversification improve ecosystem services at field, farm and landscape scales. </ItemContent></ListItem><ListItem><ItemContent> •Cropping system design should meet regional characteristics and socio-economic demand. </ItemContent></ListItem></List> Intensive agriculture in China over recent decades has successfully realized food security but at the expense of negative environmental impacts. Achieving green transformation of agriculture in China requires fundamental restructuring of cropping systems. This paper presents a theoretical framework of theory, approaches and implementation of crop diversification schemes in China. Initially, crop diversification schemes require identifying multiple objectives by simultaneously considering natural resources, limiting factors/constraints, and social and economic demands of different stakeholders. Then, it is necessary to optimize existing and/or design novel cropping systems based upon farming practices and ecological principles, and to strengthen targeted ecosystem services to achieve the identified objectives. Next, the resulting diversified cropping systems need to be evaluated and examined by employing experimental and modeling approaches. Finally, a strategic plan, as presented in this paper, is needed for implementing an optimized crop diversification in China based upon regional characteristics with the concurrent objectives of safe, nutritious food production and environmental protection. The North China Plain is used as an example to illustrate the strategic plan to optimize and design diversified cropping systems. The implementation of crop diversification in China will set an example for other countries undergoing agricultural transition, and contribute to global sustainable development.

玉米收获机分禾与摘穗装置性能仿真分析

In the design of corn combine harvester, there is a high demand for customization and diversification in China. Aiming at the problems of backward design method, lack of design knowledge and long product development cycle, the discrete beam method is used to establish the corn plant model. The model of sub-device and the vertical and horizontal roller picking device is established by using UG, and the virtual prototype model is established by using ADAMS software. Meanwhile, the simulation experiments on the kinematics and dynamics performance of the separating device, the corn plant and the picking roller are carried out, and the simulation results are verified by field experiments. Through this method, the design parameters of the separating device and the picking roller are serialized, the method of evaluating the separating performance and the picking performance is provided, and the development and design cycle is shortened, which provides certain reference and theoretical basis for the development and design of the corn harvester header.

How does economic policy uncertainty affect corporate diversification?

Economic policy uncertainty (EPU) is positively associated with corporate diversification in China between 2001 and 2007. EPU’s positive impact on diversification is significant only for large and medium cap firms. High EPU is associated with higher diversification; the effect of EPU on diversification by state-owned enterprises (SOEs) is greater than for non-SOEs. Diversification of firms with a high number of equity analysts and equity reports increases during high EPU. Diversification actively mitigates economic policy-related risks, enhancing firm performance. Our results are robust to different measures of EPU and corporate diversification and remain significantly unchanged when dealing with endogeneity.

There “ain't no mountain high enough”?: The drivers, diversity and sustainability of China's Rhodiola trade

Ethnopharmacological relevanceAcross Asia, Rhodiola species have been used in Bhutanese, Mongolian, Nepalese, Kazakh, Kyrgyz and Uzbek traditional medical systems. China is globally significant in terms of Rhodiola species diversity, with over 60% (55 species) of the world's 90 Rhodiola species, including 16 species found nowhere else in the world. Since the late 1980's there has been a shift from relatively low demand for infusions using chopped dried Rhodiola roots, to high 21st century demand for a wide variety of processed products. China's trade in Rhodiola products is now very diverse, with use in cosmetics and foods in addition to herbal products. Rhodiola crenulata (Hook.f. & Thomson) H.Ohba is the most widely traded species in China. In addition to R. crenulata and Rhodiola rosea L., 19 Rhodiola other species are used. Aims of the studyThese were to: (i) better understand why adulteration occurs in Rhodiola products; (ii) become more aware of what drives the growing market demand for Rhodiola products in China; (iii) find out whether increased demand is reflected in wholesale prices for Rhodiola raw materials traditional medicine markets; (iv) to examine Rhodiola supply chains and (v) given that wild populations are the primary supply source, to review the implications of growing demand for conservation and sustainable use. Materials and methodsFirstly, we assessed growth in the diversity of Rhodiola products using three approaches: (i) by assessing patent applications for Rhodiola products in China (1990–2019); (ii) in 2018, through on-line searches of CFDA (China Food and Drug Administration) records for medicines and dietary supplements that had Rhodiola as an ingredient and (iii) by visiting retail stores in 2018 and 2019 to assess the diversity of commercial Rhodiola based products in trade. Secondly, we visited traditional medicine markets in Yunnan, Sichuan, and Qinghai provinces to investigate the trade in Rhodiola (folk taxonomy, trade names, prices, source areas, levels of processing and grading). Thirdly, we analysed the wholesale price data for Rhodiola raw materials in trade over a 16-year period (2002–2018). Fourthly, as most products come from wild collected Rhodiola species, we documented the extent of Rhodiola cultivation in China. ResultsInternational exports of Rhodiola products from China, particularly extracts, is a major driver of commercial trade. One proxy indicator of Rhodiola product diversification in China has been the rapid rise in patent applications from single applications in 1990 and 1991, to a peak of 1017 patent applications in 2015. Wholesale price data from 2002 to 2018 shows a steady increase in wholesale prices. As the growing market for Rhodiola products in China is currently supplied entirely from wild collection, there are justifiable concerns about sustainability. Commercial cultivation needs to expand to meet future demand. ConclusionsIn contrast to Europe and North America, where R. rosea is the focal species in commerce, the trade in Rhodiola products in China is much more diverse. In the face of growing demand, both effective conservation of wild populations and cultivation are needed.

Portfolio Optimization and Diversification in China: Policy Implications for Vietnam and Other Emerging Markets

ABSTRACT This article is conducted to examine risk, return, and portfolio optimization at the industry level in China over the period 2007–2016. On the ground of the classical Markowitz framework for portfolio optimization, the mean-semivariance optimization framework is established for China’s stock market at the industry level. Findings from this study indicate that healthcare sector plays a significant role among 10 industries in China on a stand-alone basis. In addition, a significant change of rankings among the sectors in term of risk is found when the mean-semivariance optimization framework is used. We also find that utilizing this new framework helps improve the optimal portfolios in relation to performance, measured by Sortino ratio, and diversification. A simulation technique, generally known as resampling method, is also utilized to check the robustness of the estimates. While the use of this resampling method appears not to improve the performance of optimal portfolios compared with the mean-semivariance framework for China, there is a remarkable advance in diversification of the optimal portfolios. Implications for investors and the governments in Vietnam and other emerging markets have emerged from the study.
