The work presents the results of quantitative assessment of heavy metals (HM) content in bottom sediments of the coastal zone near the Karadag nature Reserve. The data were obtained as a result of field studies in 2016-2018. Estimated СС and Cо coefficients and Zc were calculated. It was shown that arsenic concentration limits were exceeded everywhere in the samples. The nickel, lead, copper and zinc limits were found to have been exceeded in some locations. Ecological and geochemical assessment of water and bottom sediments quality in the section of Karadag water area has been made.

The article systematizes the idea of the participants’ interaction in thr infrastructure projects of municipal-private partnerships through an ecosystem approach. Required and non-mandatory project participants, as well as an algorithm for their interaction in the framework of the municipal-private partnerships’ ecosystem, which is classified as “Ecosystems of infrastructure partnership” in the article, are identified. A methodological apparatus has been developed and organizational models for the construction or reconstruction of the municipal-private partnerships infrastructure projects are formed. The models are proposed to be divided into basic and varied, the latter are essentially summary and may include from one to three optional elements.

The article developed a methodology for assessing the rate of reproduction of the social infrastructure of agriculture. For this, a list of indicators has been defined that characterize the rural social infrastructure of the Russian Federation for 2009-2018; their analysis was carried out and index values were determined; formulas for calculating three integral indicators have been developed, reflecting the commissioning of objects of rural social infrastructure, communal services and areas equipped with communal networks; on their basis, the rates of reproduction of the social infrastructure in the industry were calculated; recommendations on the application of the obtained data are given.

Lomban is a tradition of the Jepara people in which is carried out one week after Eid al-Fitr. Lomban is a party of fishing communities in the form of sea alms, which is now supported by the people of Jepara and outside Jepara. The center of the competition is located at Kartini Beach. This competition activity is related to the environment and marine conservation, especially in protecting the environment. The existence of the lomban tradition shows the continuity of fish living in the sea and the harmony between the marine environment, humans, and God. The lomban tradition in which there is a buffalo head larungan shows the concern of fishermen, community members, and local governments for the marine environment. With this tradition, there is an awareness that in taking fish in the sea and the natural wealth of the sea must pay attention to the survival of marine life. The marine economy taken must pay attention to the conditions of the marine environment and not damage the sea. Through the efforts of the lomban tradition, it is hoped that environmental conservation will be well maintained. Keywords: Lomban, preservation, environment, sea, Jepara.

Inertia is an attribute of various systems, including sustainable development. The study of the inertia of sustainable development as a complex industrial-ecological and socio-economic supersystems is necessary to give due depth to theoretical explanations of the processes implemented in the practice of regulating industrial production, economic relations that determine the environmental load, the level of consumption of natural resources, to identify qualitative and quantitative relationships between factors of changes in structural proportions in production and consumption, their sources and relocation productive forces. The result if the study of inertia as a quality of macroeconomic structural changes, immanent to sustainable development, should be a knowledge of the forms of the transition of economic achievements of society into environmental ones. The study of sustainable development inertia is intended to improve the forecasting of various processes of interaction between man and the environment through the use of productive forces. The content of structural inertia of sustainable development can be revealed through the dynamic and actively transforming properties of structural shifts no less than through the conservatism of the structure of the economy, therefore, the creation of conditions for the regulated implementation of structural inertia, its transition into its opposite – acceleration of positive structural transformations – is associated with the regulation of economic relations in the system of environment management, production and consumption of natural resources, dynamization of changes in structural proportions between raw materials production and its processing, to overcome delaying the formation of new structural elements.

High quality is the direction of development, innovation drives high-quality development, and interest incentives drive innovation. Existing studies have shown that executive equity incentives can increase the financial performance of enterprises. Therefore, can executive equity incentives promote the high-quality development of enterprises, thereby improving the quality of industrial development? This paper takes China’s knowledge-intensive enterprises as a sample from 2015 to 2019. On the basis of using the LP semiparametric estimation method to measure the total factor productivity of the enterprise, in accordance with the intermediary effect test procedure, the stepwise regression method is used to study the innovation-driven effect of the executive equity incentives on the quality of enterprise development. The study found that executive equity incentives have an inverted U-shaped impact on the high-quality development of companies, with 20% being the optimal ratio. There is a partial mediating effect in corporate innovation activities on this transmission path. Based on this, suggestions are made to share residual income with senior management and build a high-quality innovative production chain.

Coastal zone is very vulnerable to the impacts of climate change. The increase of sea wave and sea level rise threaten coastal zone. The purpose of this study is to determine trends of significant wave height and sea level in the southern waters of the special region of Yogyakarta. The data used consists of daily significant wave height from 2010-2018, weekly absolute dynamics topography from 2005-2018 and daily surface wind from 2010-2018. Trends of significant wave height and sea level were analyzed by using linear regression. The results showed that significant wave height during the east season until the second transition season was higher than the west season and the first transition season. Vice versa, sea level during the east season until the second transition season was lower than the west season and the first transition season. Trends of significant wave height has increased of 0.63 cm/year, meanwhile sea level rise reached 0.82 cm/years.

The new growth points of two major industries—tourism industry and logistics industry—can be fully utilized to reach the effect of 1+1>2 by promoting their collaborative development. It is suitable to boost the tourism logistics collaborative development in Wuhan, which integrates various advantages in traffic location and resources, tourist market and industrial development, policy opportunity, etc. In this research, the tourism logistics collaborative development model in Wuhan was expounded from three aspects: planning and design of tourism logistics route, integrated design of tourist commodity logistics, and tourism waste logistics collaborative treatment system, expecting that Wuhan can grasp the opportunity and provide policy support, technical support and financial support to promote the collaborative development of the tourism logistics industry and accelerate the healthy development of Wuhan.
