Tax Incentives, R&D Manipulation, and Corporate Innovation Performance: Evidence from Listed Companies in China
Authors: Sun Wenyan , Yin Kedong , Liu Zhe
Published: October 2021

This study investigated the R&D manipulation of Chinese listed companies under preferential tax policies based on the bunching approach. On this basis, differences in organizational performance aspirations were used to distinguish firm heterogeneity. This was to clarify how tax incentives affected firm innovation performance. The empirical results show that preferential tax policies can effectively reduce the actual tax burden of high-tech enterprises. Some companies have enjoyed corporate income tax breaks by manipulating R&D spending. The counterfactual estimate of R&D intensity shows that the elasticity of taxable income of R&D investment of listed companies in China is between 0.55 and 0.8. The elasticity of taxable income of manufacturing enterprises is between 0.6 and 0.75. Furthermore, within the R&D operating range, firm-level variations will affect innovation performance. The incentive effect of R&D activities of enterprises with a negative organizational performance aspiration gap is higher than that of enterprises with a positive organizational performance aspiration gap. The conclusion provides the basis for the country to improve preferential tax policies for high-tech enterprises.

Authors: Mazumder Mithil , Yun Jihyeon , Lee Soon-Jae , Jeong Kyu-Dong
Published: October 2021

The use of intelligent compaction (IC) in asphalt overlay includes the use of double-drum IC rollers, a roller measurement system, global position system (GPS) radio/receiver/base station, infrared temperature sensors, and an onboard computer reporting system. GPS based mapping and optional feedback control help to overcome the drawbacks associated with conventional compaction such as identifying soft spots, achieving consistent roller patterns, and monitoring asphalt surface temperature and levels of compaction with adequate quality control or quality assurance (QC/QA). Cost-effectiveness of both compaction types was measured in terms of initial and roadway lifecycle cost based on the cost inputs received from South Korea and other published literatures. Roadway lifecycle cost was reported based on the improvement in in-place density, smoothness, and fatigue life. The results of this study showed that: (1) with IC an approximate 4.1% initial cost reduction can be achieved compared to conventional compaction; (2) QC/QA cost is found to have the most significant effect on the higher initial cost of conventional compaction compared to other associated costs whereas intelligent roller cost is the vital cost category for IC; (3) improvement of in-place air voids and density due to the IC has shown that at 97% field density (or at 3% air void content) the State Highway Agency can save approximately 44% over a 20-year service period; and (4) agency cost is observed to be reduced by approximately 62% with the IC method based on the 25-year analysis period due to the increase in fatigue life.

Authors: Li Ding , Pérez-Sánchez María de los Ángeles , Yi Shun , Parra-Lopez Eduardo , Bu Naipeng (Tom)
Published: October 2021

The importance of a sustainable labor market is a critical and fundamental point for many developing countries, where global competitiveness is based on cheap labor. The aim of this empirical–analytical study, framed in China in the research context, is to approach this hot topic from the lens of household wage differences between generations. Using cross-sectional data, consisting of the China Dynamic Migrant Survey and Oaxaca-Blinder decomposition methods and quantiles, to analyze the data results confirmed the differences in wages between two generations of peasant and urban workers. Moreover, a distinctive tapering in the pay gap occurred among the new generation. Fundamentally, a big gap exists in the rate of return on education between urban and rural labor. According to the results of quantile decomposition, the old generation of peasant and urban workers demonstrate anti-discriminatory phenomena at very low and very high scores.

Authors: Saragi Rizalina Tama , Juanes Marcos , Pinacho Ruth , Rubio José Emiliano , Fernández José A. , Lesarri Alberto
Published: October 2021

The homodimers of transiently chiral molecules offer physical insight into the process of molecular recognition, the preference for homo or heterochiral aggregation and the nature of the non-covalent interactions stabilizing the adducts. We report the observation of the benzyl mercaptan dimer in the isolation conditions of a supersonic jet expansion, using broadband (chirped-pulse) microwave spectroscopy. A single homochiral isomer was observed for the dimer, stabilized by a cooperative sequence of S-H···S and S-H···π hydrogen bonds. The structural data, stabilization energies and energy decomposition describe these non-covalent interactions as weak and dispersion-controlled. A comparison is also provided with the benzyl alcohol dimer.
The Stem-Loop I of Senecavirus A IRES Is Essential for Cap-Independent Translation Activity and Virus Recovery
Authors: Wang Nana , Wang Haiwei , Shi Jiabao , Li Chen , Liu Xinran , Fan Junhao , Sun Chao , Cameron Craig E. , Qi Hong , Yu Li
Published: October 2021

Senecavirus A (SVA) is a picornavirus that causes vesicular disease in swine and the only member of the Senecavirus genus. Like in all members of Picornaviridae, the 5′ untranslated region (5’UTR) of SVA contains an internal ribosome entry site (IRES) that initiates cap-independent translation. For example, the replacement of the IRES of foot-and-mouth disease virus (FMDV) with its relative bovine rhinitis B virus (BRBV) affects the viral translation efficiency and virulence. Structurally, the IRES from SVA resembles that of hepatitis C virus (HCV), a flavivirus. Given the roles of the IRES in cap-independent translation for picornaviruses, we sought to functionally characterize the IRES of this genus by studying chimeric viruses generated by exchanging the native SVA IRES with that of HCV either entirely or individual domains. First, the results showed that a chimeric SVA virus harboring the IRES from HCV, H-SVA, is viable and replicated normally in rodent-derived BHK-21 cells but displays replication defects in porcine-derived ST cells. In the generation of chimeric viruses in which domain-specific elements from SVA were replaced with those of HCV, we identified an essential role for the stem-loop I element for IRES activity and recombinant virus recovery. Furthermore, a series of stem-loop I mutants allowed us to functionally characterize discrete IRES regions and correlate impaired IRES activities, using reporter systems with our inability to recover recombinant viruses in two different cell types. Interestingly, mutant viruses harboring partially defective IRES were viable. However, no discernable replication differences were observed, relative to the wild-type virus, suggesting the cooperation of additional factors, such as intermolecular viral RNA interactions, act in concert in regulating IRES-dependent translation during infection. Altogether, we found that the stem-loop I of SVA is an essential element for IRES-dependent translation activity and viral replication.

Published: October 2021

While prior research has explored various physiological consequences associated with assistive device use for ambulation, limited research has specifically explored the impact of mobility dog partnership on human kinematics. This descriptive study examined the impact of mobility dog partnership on kinematics of individuals in the normal young adult population. Sixteen participants were video recorded while walking in a straight line for 3.7 m (12 feet) under three different conditions (ambulating with no device, ambulating with a standard cane on the left side, and ambulating with a mobility dog on the left side). Differences between joint angles under each of the conditions were analyzed. Statistically significant differences were found in left elbow flexion when comparing ambulating with a cane versus ambulating with no device; left shoulder abduction when comparing ambulating with a cane versus ambulating with a mobility dog, ambulating with a mobility dog versus no device, and ambulating with a cane versus no device; and left hip extension when comparing ambulating with a mobility dog versus no device, and when ambulating with a mobility dog versus a cane. These findings suggest that providers should evaluate and monitor potential negative impacts of assistive devices such as mobility dogs on human kinematics.

Published: October 2021

This study aimed to evaluate the supplementation (of drinking water) effects of L-Carnitine (LC) and/or calf thymus extract (TE) on immunity, antioxidant, duodenal histomorphometric, growth, and economic performance of Japanese quail. Six hundred, one day old unsexed quail were divided into four groups, the control group (G1) received plain drinking water, while G2, G3, and G4 were supplemented with LC and/or TE, respectively. The treated groups recorded a significant (p < 0.05) improvement in the final body weight, weight gain, feed conversion ratio, phagocytic activity %, phagocytic index, lymphocytes %, and plasma glutathione level compared to the G1. On the other hand, these supplementations significantly lower the mortality rate %, heterophil %, H/L ratio and plasma malondialdehyde level of the supplemented groups relative to G1. The supplemented groups recorded a non-significant increase in duodenal histomorphometric parameters (villous height, villous width, surface area, and crypt depth) relative to G1. Generally, LC and/or TE improve the values of economic profile (total returns, net profit, total return/total costs %, etc.) in treated groups compared to the control one. In conclusion, L-carnitine supplementation was more effective than TE or their combination with TE in the immunological, anti-oxidative, growth, and economic performance.

Authors: HAYRAN Osman , YIGIT Pakize
Published: October 2021

Aim: The aim of this study is to compare performance rankings of OECD countries with the MULTIMOORA method by using the health policy responses and various variables related to COVID-19.
Material and Method: Study includes cross-sectional data of 37 OECD countries. Data regarding eleven variables about the current population health status in these countries are collected from open reliable sources. CO- VID-19 health policy responses of the countries recorded in the OECD database were scored and weighted scores computed by using Fuzzy AHP method. The performance rankings of OECD countries were determined by the MULTIMOORA method with use of all variables.
Results: Among the policy responses highest ranking score was computed for “mobilizing and protecting health workers” and the lowest score for “increasing access to mental health services” (0,172 and 0,042 points respectively). According to the results of performance rankings by MULTIMOORA, New Zealand was located in the first and Belgium in the last place while Turkey has been the eighteenth.
Conclusion: Study findings can be concluded as the COVID-19 performance of the Eastern countries is better than the Western developed countries with the exceptions of Iceland and Czechia. However, it is difficult to draw justifying conclusions about the success or failure of a country in managing the pandemic due to the complex interactions between various variables and the cross-sectional nature of the study data.

Authors: Ortiz Ana Verónica , Moroni Pablo , Mirra Fabiana , Villanueva Espinoza Rosa María , O'Leary Nataly
Published: October 2021

Morphological boundaries between South American species of Euphrasia L. are controversial, rendering determination of specimens an arduous task. In this context, a comprehensive taxonomic revision of Euphrasia in South America is here provided for the first time. This study, based upon a classical morphological study of ca. 400 herbarium specimens, supports the recognition of eight species and one subspecies distributed in the Andean regions of Argentina, Bolivia, and Chile. From among native species, six belong to section Trifidae Benth. and one to the monotypic section Paradoxae Pugsley, endemic to Juan Fernández Islands; one adventive species, E. officinalis L., belongs to the section Euphrasia. The previously misunderstood presence of E. cockayniana Petrie is here untangled, and, consequently, the species is excluded from South America. A key to all Euphrasia taxa in South America, plus morphological descriptions, nomenclature items, geographical distribution and maps, habitat notes, illustrations, photographs, and discussion notes are included for the nine taxa. Eleven names are here synonymized, and lectotypes are designated for E. andicola Benth., E. debilis Wettst., E. flavicans Phil., E. intricata Phil., and E. philippii Wettst. Euphrasia andicola is reported for the first time for Argentina. This collaborative effort will represent a baseline for further investigations on Euphrasia in South America.
PLANNING AND SELF-CONTROL IN THE COGNITIVE REGULATION OF PRIMARY SCHOOLCHILDREN WITH UNBALANCED HERITAGE BILINGUALISM
Authors: Khotinets V.Yu. , Gilmullina L.G.
Published: October 2021

The article concentrates on searching for missing knowledge about the influence of unbalanced heritage (inherited) bilingualism on the cognitive regulation of a child with high speech activity in a second (Russian) language. The study involved junior schoolchildren 7-8 years old: 1) the main group (N=22) - the children with unbalanced heritage bilingualism (who inherited the Tatar language with different levels of linguistic competence in respect of native and Russian languages), 2) the comparison group (N=30) - monolingual children with speech activity in Russian, who study in educational institutions of the Udmurt Republic. According to the results of empirical research, along with a greater severity of the planning indicator the plasticity and flexibility of the cognitive regulation system of the bilinguals has been established, which provides the integrative potential for regular opportunities. We assume that these advantages arise from the activation of bilingual interaction of language systems.

The article discusses the issues of self-regulation development in young adolescents. It reveals the structural elements of self-regulation process, characterizes the structural-functional and content-psychological aspects of self-regulation. The presented structure served as the basis for the analysis of self-regulation of children of early adolescence, taking into account the changes that occur with children at this age stage. The following features of self-regulation of young adolescents in different spheres of their personal development have been identified: a decrease in the ability of self-regulation due to changes occurring at the physiological level and in the functioning of the nervous system of the young adolescent; an increase in the young adolescent's ability to consciously and arbitrarily regulate the motivational sphere of personality in combination with weak arbitrariness of learning motivation; the emergence of the ability for independent volitional regulation of activity; a decrease in the ability for self-regulation in the emotional sphere due to the emergence of a tendency to self-reinforcement, a tendency to affectation in behavior; connection of the adequacy of the image of the "I" and the ability to self-regulation.
Identidade e testemunho em K. - Relato de uma busca, de Bernardo Kucinski
Authors: Silva Ricardo Augusto Garro
Published: October 2021

O romance K. – Relato de uma busca, de Bernardo Kucinski, publicado em 2014, inicia-se com cartas recebidas pelo narrador direcionadas à sua irmã desaparecida durante a ditadura que governou o Brasil entre 1964 e 1985. Esse episódio resgata e põe em relevo uma memória dolorosa de perdas e irreparáveis danos. O desaparecimento, debitado pelo narrador à ação de agentes policiais ligados ao Estado, assume, desde o início, o tom trágico de um crime não redimido pela ação da Justiça, ao mesmo tempo em que articula o presente da narrativa à história recente do Brasil. Esta comunicação analisa a capacidade da ficção de reescrever, em alguma medida, a história, além disso, espero avaliar a conexão da biografia do escritor com narrador do romance.

A partir da análise da novela Viagens de Ahasverus à terra alheia em busca de um passado que não existe porque é futuro e de um futuro que já passou porque sonhado, de Samuel Rawet, publicada em 1970, esta comunicação abordará a forma com que o escritor – nas palavras de Gilles Deleuze e Felix Guattari, que cunharam a expressão “literatura menor” – representa, em seus escritos, a população hegemônica. Noutras palavras, como a minoria é representada na obra de Rawet. Dessa forma, procuro entender a radicalidade do próprio estranhamento vivenciado por grupos minoritários, em sua manifestação literária.

Democracia política e democracia econômica nos duzentos anos do Brasil
Authors: Amato Lucas Fucci
Published: October 2021

Este artigo pretende apresentar um balanço histórico e desenhar um programa institucional centrado na interdependência entre democracia política e democracia econômica no contexto brasileiro. A obra de Roberto Mangabeira Unger fornece o quadro conceitual estruturante tanto para a explicação das oportunidades e dos constrangimentos na trajetória institucional do país quanto para a imaginação de alternativas ao desenho jurídico atual das instituições políticas e econômicas. A tese básica do texto é de que as formas jurídicas prevalentes desde a independência subordinaram as demandas democráticas à institucionalidade ora mais liberal, ora mais social e desenvolvimentista. Agora, para garantir e aprofundar a democracia política, cabe institucionalizar uma democracia econômica. A democratização política afirmada pela Constituição de 1988 gera hoje uma crise de expectativas insatisfeitas que demanda como resposta a reforma institucional do Estado e da economia de mercado, com vistas a retomar o desenvolvimento econômico em bases mais descentralizadas e includentes.

Published: October 2021

The number of green energy options in different fields is growing because of the need for reducing energy consumption and eliminating gas emission. One of these options is the use of eco-friendly cars produced by various manufacturers. Given the many available options and conflicting evaluation criteria, evaluation of such options becomes complex, and different multi-criteria decision-making (MCDM) approaches have been used to select the most suitable car in terms of eco-friendly car selection. Previous research has been somewhat limited with respect to consideration of interdependencies between evaluation criteria and multi-levels of preference. This paper proposes a new integrated MCDM approach with the capability for considering interdependent criteria for eco-friendly car evaluation and different levels of preference. An analytic network process (ANP) will be used to evaluate the levels of importance of interdependent criteria, and ELECTRE III will be modeled to include thresholds of preference. The introduced model, based on twenty-eight evaluation criteria, was demonstrated in a case study dealing with five alternative electric and hybrid cars. The results from this model were compared to a traditional decision-making method and better results were obtained from the model. The model can help users make proper decisions regarding their future car options in a comprehensive manner. Sensitivity analysis showed the robustness of the model under different setups.

Authors:   Department of Civil Engineering, Nevsehir Haci Bektas Veli University, Nevsehir, 50300, Turkey., Çelikten Serhat
Published: October 2021

In this work, 21 different raw perlite (RP) -based geopolymer mortars (RPGMs) were manufactured. Blast furnace slag (BFS) was replaced by RP in 7 different proportions with respect to the CaO/SiO2 oxide ratio of RP and BFS mixture in the RPGMs. Sodium hydroxide (NaOH= 5, 10, and 15 M) was used as alkaline medium for geopolymer synthesis in the RPGMs. The ultrasound pulse velocity (Upv), flexural strength (ffs) and compressive strength (fcs), water absorption, acid and sulfate durability of the RPGMs are investigated. The test results revealed that the BFS improved the mechanical properties of RPGMs for the low and medium alkaline medium of 5M and 10M, respectively. On the other hand, BFS had negative effect on the mechanical properties of RPGMs produced at a high alkaline medium of 15M. Moreover, the BFS improved the acid and sulfate durability of the RPGMs.

The article deals with the local plastic deformation analysis after cold forming. The technology of drawing seamless steel tubes was used to obtain cold-formed samples. The tubes were manufactured by a Tinius Olsen 300ST tensile tester with a 6 ° and 12 ° die drawn without and with an inner mandrel. Based on orientation size recalculated by stereology and applying Monte Carlo method a mathematical conversion model was developed. Implemented model together with surface measurements and structure characteristics were used to get the orientation to the size of the deformation. Thus, the actual (logarithmic) deformations and local stresses were determined. Comparison of experimentally measured values of the actual local plastic deformation with the deformation calculated found on the model simulation in the Deform program defined the significance of the differences assessed by means of a statistical T-test. All differences in the values of the local plastic deformation with respect to the position were evaluated as statistically insignificant and therefore the difference between the experimental calculation and the simulation is random.

This investigation reports the effect of mechanical deflector during coating on the mechanical properties of the Electroless Ni-P deposits. Micro hardness of the electroless Ni-P deposits was measured using shimadzu micro hardness measuring unit employing a diamond indenter and pin-on-disc wear tester was used to measure the wear resistance of the deposits. The characteristics of deposits produced in presence of mechanical deflector are found to be superior from those produced using conventional deposition techniques. Enhancement in properties are correlated with modified crystallinity and the conversion of Ni-P in to possible phosphides in the presence of mechanical deflector. It has been noticed that the coating efficiency has 30% hike with mechanical deflector. Annealing at 350ºC has reached the maximum hardness of 950 Hv and subsequent increase in wear resistance.

User experience evaluation approach is the major key to adapt the new trends and technology. The product launch is based on the various opinions of users and availability of product. The first impression about the product makes successful sales, which is analysed with UX (User eXperience) design. Before developing / launching the product, have to evaluate the user experience model by online sources. The opinion/sentimental analysis are the way to capture the people’s opinion about the product. Rating, page session, website page views, and number of buyers or users are evaluated as a graph model and predict the requirement of the product. This process makes the product’s benefits. The previous work utilizes the Markov Chain Monte Carlo (MCMC) Method to model the UX design. In this proposed research work, the opinion mining approach is used to get the dataset from Google analytics. This dataset is model using Kernel based Naïve Bayes Classification algorithm and the prior & posterior probability is calculated by MCMC (Markov Chain Monte Carlo) techniques. Classification approach takes the training and testing data. Here the confusion matrix is used to create the UX evaluation model’s accuracy. By this proposed algorithm, it summarized the positive and negative opinion then we can calculate the accuracy of the system and it easily identifies the user opinion. This proposed UX design model improves the result as compared to the previous MCMC method. The data mining based sentimental classification is done with the help of MATLAB 2018a tool.

Disruption tolerant networks (DTN) are networks that provide unguided technologies. Solar technologies and Radio frequencies are used to operate the network. In DTN networks the connectivity does not last for a long time and they do not provide end to end connectivity. Therefore it uses store and forward technique to forward the packets to the destination nodes. When N number of nodes is participating in the network, each node receives packets from the previous node and sends acknowledgment to the sender node. Time delay occurs on receiving and sending acknowledgment continuously. Collision occurs due to the congestion in the network. Due to the irregular connectivity in the network, the compromised nodes try to drop the whole packet or part of the packet. The Blackhole and Greyhole attacks occur due to the packet loss. Optimized algorithm can be used to solve the above attacks. By using CAT Swarm optimization algorithm, the attacks can be prevented and it minimizes the Time delay in delivering the packets.

The ‘Orthogonal frequency division multiplexing (OFDM)’ is a well-accepted and effective technology employed today and in future wireless communication systems. The combinations of OFDM and ‘multiple-input multiple-output (MIMO’) offer high quality of services and better throughput. The multicarrier OFDM system experiences a high ‘peak-to-average power ratio (PAPR’), which is the major issue in the OFDM scheme and must be truncated to achieve trustworthy communication. Due to high PAPR in a signal to be transmitted, the power amplifier in the transmitter section enters into saturation region and amplifies the signal nonlinearly, resulting in loss of orthogonality and ultimately in ‘inter-carrier interference (ICI)’. In this article, the 'iterative clipping and filtering (ICF)' method is proposed to minimize the PAPR in the OFDM system. The simulation is carried out using MATLAB (version 2014b). The result of the proposed ICF method and the ‘selective mapping (SLM)’ scheme is analyzed and compared. From the analysis, it is shown that the proposed ICF technique is more suitable for minimizing the PAPR effectively without affecting ‘bit error rates (BER)’ much and the simplicity of the system. The simulation result of the proposed ICF scheme using ‘Quadrature Phase Shift Keying (QPSK)’, FFT size of 128, and clipping and filtering level up to 6 shows that the proposed ICF scheme for clipping level of 6 reduces PAPR to 5dB. Also, the BER is minimized at the level of 3×10−5 at 12 dB SNR.

This article aims in exploring the dry sliding wear performances on the aluminum (AA7075) metal matrix composites reinforced with molybdenum disulphide which is a solid lubricant using response surface methodology (RSM). Specific Wear Rate (SWR) for the AA7075 pure alloy, AA7075+2wt% molybdenum disulphide and AA7075+4wt% molybdenum disulphide were measured according to ASTM G99 standards in pin-on-disc apparatus. Design of experiments was selected with changed parameters like the varying percentage of molybdenum disulphide (%), applied load (N), and sliding velocity (m/s) based on Central Composite Design in response surface methodology considering them as continuous factors. Experiments for the specific wear rate of pure alloy and the composites were conducted. The volume loss was measured using the pin-on-disc apparatus from which the specific wear rate value was calculated. The obtained results are analyzed and a mathematical model was formulated using the response surface methodology. The optimum level parameters for the specific wear rate has been identified and the results of the experiment specify that the sliding velocity and molybdenum disulphide percentage have a substantial role in controlling the wear behaviour of composites when compared with the other parameter. The optimum condition for the specific wear rate was identified and experimented with for studying the result.
STRATEGIC DIRECTIONS OF DEVELOPMENT OF BIOLFUELS PRODUCTION FROM AGROBIOMASS OF AGRICULTURAL ENTERPRISES OF UKRAINE
Authors: TOKARCHUK Dina
Published: October 2021

The article substantiates that the agricultural sector of Ukraine has a significant bioenergy potential. The first component of this potential is agricultural crops: traditional (cereals, sugar beets, sunflowers, rapeseed, etc.), which can be used for the production of bioethanol, biodiesel and energy crops (willow, poplar, miscanthus), which are used for the production of solid biofuels or second generation biofuels. The second component is organic waste from crops and livestock, which is a potential raw material for the production of biogas and solid biofuels.
An algorithm for the development and implementation of a strategy for the development of biofuel production from the bioenergy potential of agrobiomass of agrarian enterprises has been offered with an emphasis on the obligation of its constant monitoring and correction to achieve the
planned indicators. The expediency of using the SWOT-analysis methodology in the development of this strategy has been substantiated.
The strengths and weaknesses of agricultural enterprises have been analyzed from the point of view of bioenergy development. For this, there were assessed their profitability and efficiency, the dynamics of growing of agricultural crops that can be used for the production of biofuel, and the volume of organic waste generated. Among the main strengths are strong bioenergy potential, weaknesses are resistance to change and the reluctance of managers to take risks by investing a lot in biofuel production. Analysis of the external environment showed the presence of both favorable (cooperation with international financial organizations, an increase in demand for bioenergy raw materials) and unfavorable factors for the development of bioenergy potential (high cost of equipment for bio-production, unfavorable credit policy, etc.).
The combination of the strengths and weaknesses of the internal environment, as well as the opportunities and threats of the external environment of agricultural enterprises in bioenergy made it possible to identify four potential strategic directions for the development of using bioenergy potential of agrobiomass: organization of the production of all types of biofuels (liquid, solid, gaseous) by enterprises, energy autonomy; increasing of bioenergy potential in an intensive way, organizing the production of those types of biofuels for which bioenergy potential is the largest; building up bioenergy potential in an extensive way, selling bioenergy crops to Ukrainian biofuel producers; enterprises do not increase their bioenergy potential, they remain producers of only those agricultural crops for which there is a demand in Ukrainian and the world markets.

The article deals with the meaning of the concept of «intellectual investment». It was found that this economic category is quite diverse and most foreign and domestic scientists give only a general definition. Based on the studied approaches to understanding the essence of intellectual investment, the authors provide their own interpretation of this economic category. So, intellectual investment is any investment in intangible assets: training and retraining, research and development, transfer of know-how, creation of innovative products for additional economic benefits. A number of features that distinguish investments in intellectual capital from other types of investments are identified and attention is paid to approaches to the classification of types of intellectual investments.

It is established that the leading countries in the implementation of intellectual investment in 2020 are China, the United States, Japan, Britain, Germany, and the trend of increasing the share of spending on innovation is observed in such regions as Asia and the Middle East, respectively. The place of the countries in the ranking of the Global Innovation Index, which is headed by Switzerland, Sweden and the United States, followed by Great Britain and the Netherlands, is described.

The level of development of intellectual investments in Ukraine in terms of financing of innovation activities during 2016-2020, as well as in terms of receipt of applications for industrial property in Ukraine and the world is analyzed. The main negative factors that hinder the development of intellectual investment in Ukraine are assessed, and on the basis of world experience the effects that can be obtained as a result of investing in intellectual capital at different economic levels are highlighted. Due to the fact that Ukraine is losing its authority and attractiveness in the field of invention in the international arena, it is proposed to create a clear program to attract investment in intellectual capital, increase the share of budget funds for development and implementation of innovations, introduce programs to encourage the return of scientists. who previously emigrated.
